The Barrow Kings

In the oldest days of man, we were in tune with the earth. We communed with spirits, and spoke to animals. We requested favours of the earth, and performed it favours in kind. The Barrow Kings are not from those most ancient of ages, yet were alive yet to see and remember the last few dying embers of it. Their spirit-magics were strong, their wills indefatigable. When death came to grasp them, they went no unscreaming, and the Barrows they leave have trapped their spirits with their old and mouldering bones. There they remain to these modern days, awaiting, awatching, disgusted at the weaknesses shown by their distant, distant descendants. Still they jealously clutch their treasures, powers, and glories, and dream in death of days when they may yet reclaim them.

The Barrow-King's Mode of War

The Barrow Kings do not all fight in the same manner, they do not all fight with the same weapons. These are the main categories of their armaments and tactics though, and they should be equipped appropriately for such, even in death.

1 - Weapon Master - Even then, the blade had been mastered, and in an art you will not know
2 - Hexblade - Many curses were wrought in their blade, in the flesh, on their heart
3 - Sorcerer King - Mightier Magics were wrought then by Mightier People
4 - Juggernaut - Armour of Stone, Shield of Bone, Blade of Iron, Might like the Lion
5 - Nightmare Master - Not even your blackest dreams match what he sees in sleep
6 - Necromancer - Bone and Flesh, Answer the Call of their Word!
7 - Animist - A Friend of the Earth becomes mighty indeed
8 - Ravager - Axes and War-cries, bloom of flame on the Horizon and a long, long Night.
9 - Proto-Paladin - The Blessings of Ancient Gods hold strong even now
10 - Shackled - Beaten, Battered, Broken, Chained; a mouthful of sand and sand and sand

Guardians

The guardians of the Barrow King attend to them personally, or await close by their gates. They are the last line of defence between defilers and the sacred bones of Barrow King. Each Barrow King has one set of Guardians.

1 - Locus Genii
2 - Ancestor Spirits [An amorphous host]
3 - Grave-Guard [3d6]
4 - Black Knights [2d8]
5 - Guardian Familiar
6 - Animated Sentinel
7 - Curse-Bond Revenant
8 - Divine Figment
9 - Plant-Ally
10 - Avatar of the Earth

Locus Genii
The Spirit of a place, a guardian spirit against defilers and a watchful nurturer for honest seekers of truth. It cannot leave this place, but while here it has incredible power and influence. All the other spirits in the Barrow are its friends, and will serve it for a time in defence of the Barrow.
Ancestor Spirits
Not all the souls of the Departed truly depart. Some remain for any number of reasons. These ones remain in service to their lord. They will endure as long as the Lord does.
Grave-Guard
Armoured Bones and Wicked Weapons; they were the elite in their day, and though the sun has long since set on them, their skill is not diminished, and their blades still bite with power.
Black Knights
Old and Mouldering bones wrapped all about in the Black Thoughts of the Barrow King, become physical by the Strange Magicks of this place. They fight as furiously as the Barrow King imagines they should, but they are subtly shapeless and unformed, terrifying nightmare-figments given existance.
Guardian Familiar
In life, this spirit-beast never left the side of its master, and it remains here still. The long weight of ages has twisted it, and it has grown huge and fat on the energies of the place, a veritable beast fanatically determined to guard the body of its old, old friend.
Animated Sentinel
Made in semblance of man, once it might have been a mere statue, or suit of armour, but now it is an unfailing guardian, immune to the burdens of sleep and weariness.
Curse-Bond Revenent
Not all who rest dead in the Barrow do so of their own accord. These are the bodies of those slain upon the crest of the barrow, whose necks were slit open that their blood could flow down and inundate the earth of the Grave. These are those powerful in their wrath, unable to leave, unable to rest, their powerful rage granting power that can't be taken out on anyone anymore.
Divine Figment
Some say that Gods are nothing more than spirits of the World grown fat on faith and reverence. Perhaps its true of all Gods, but it is certainly true of this Spirit. It has been diminished by the march of ages and a lack of offerings, but it still blazes with power beyond a mere man.
Lignic-Ally
In the elder days of man, many were closer friends of the earth and its peoples that they are in these modern days. Some of these friendships still hold strong, even after all these years, and this Plant-Person will not suffer desecration to befall the one that was its friend in elder days.
Avatar of the Earth
The mightiest of the Spirits of the World that can wander in bodies of stone and mud, some few have been bound into service, or sometimes are motivated to repay ancient debts. In either case, they are mighty guardians indeed, to whom the earth is a willing ally, and the plants a faithful soldiery.

Minions

Minions are the various beasts and terrors of the Barrow, induced to unconscious service by the undying will of the Barrow king. Each Barrow king has a set of Minions for every 2 HD they have.

1 - Votive Dead [5d6]
2 - Skeletons [3d8]
3 - Unclean Spirits [3d4]
4 - Guardian Statues [3d4]
5 - Animated Murals [d4]
6 - Earthen-Men [3d6]
7 - Spirits of Rites [2d4]
8 - Vengeful Beasts [3d6]
9 - Elemental Motelings [3d6]
10 - Dream Figments [d4]

Votive Dead
Much like the Curse-Bonded, the Votive Dead let their blood flow for the Honour of the Barrow King. Their anger was not as potent as the rage of the Curse-Bonded, and thus they remain as more docile and impotent beings, though the presence of defilers still rouses them to anger.
Skeletons
The soldiers of the Barrow King in life, they remain in devoted service in death as well, clad in tattered armour and wielded ruined weapons. Their forms hold together as their morale does, the more the battle turns against them, the quicker they crumble as their spirits abandon the battle; but should they find smaller victories in the struggle, they will surge through wounds and blows to deadlier and deadlier effect.
Unclean Spirits
Not all Spirits are the wholesome personages of stones and earth. These Spirits are rife with muck and rot, possessing deplorable hungers and loathsome forms. They lurk in the dark corners of the earth, out of sight; and thus many will congregate in the Barrows of the Ancient Kings. They are known to bring sickness and curses, and have a particular hatred of humans, who represent everything the spirits find hateful in the world.
Guardian Statues
Coming in all manner of shapes and forms, these animated idols are purpose-built to defend the sanctity of the tomb, and their durable forms and powerful blows for their size makes them ideal sentinels. Their relative slowness and the simplicity of the spirits animating them (or at least, their lack of effort) mean that they are often-times able to be outsmarted, or outmaneuvered. The long marches of years have not been kind to them.
Animated Murals
Many Barrows contain murals of the great deeds and feats of the Barrow Kings. A few even have them enchanted to come to life in defence of those they depict. Creatures of myth clamber down from the walls, armies of tiny men flood from the pictures, glowing blades and the warriors that hold them finding new life in their enchantments.
Earthen-Men
Tiny spirits of the earth given vessel in mud-moulded forms like that of men. They have been taught that they are the defenders of the King in death, and that they will tolerate no defilers. Their bodies mold as their needs dictate, though unconsciously, and they fight unyieldingly, unaware that there is even such a thing as surrender.
Spirits of Rites
Some of the sacrifices that occur during the funerals of Barrow Kings aren't solely for the glory of the dead. Some bring new spirits into being; or rather, reshape present spirits into new and horrendous forms. They are bound to the implements of ritual, the bloody knife, the stained altar, the drenched pit. They animate them in anger when defilers approach, but they are confused and lost, unaware. They will destroy what they don't understand, and back down against nothing, they are more akin to animals than most spirits. 
Vengeful Beasts
All sorts are sacrificed at the funerals of Barrow Kings, not least of all animals. Oxen, horses, serpents, wolves, dogs, fish, cats, all kinds meet the blade throat-on in honour of the departed. Their spirits remain in their bodies, and their ragged, undead forms are another line of defence between the glorious bones of the Barrow King and those who would defile them.
Elemental Motelings
Just tiny, cute little elementals. Be careful though, in swarms, they have all the capabilities of their greater cousins, a fact of which they are well aware.
Dream Figments
The dead do not rest undreaming in barrows. Sometimes, fragments and shards of dreams slip from their hollow skulls, manifesting as amorphous, indistinct mists, shapes forming and solidifying then dissipating in an instant within the mist. They prey on men, hoping that by taking the spirits of the living, they might make themselves more real. They take on the aspects of what they slay, yet they will never really attain life, and this makes the mightiest of them angry and wrathful.

How Shall Ye Know the Barrow?

Great heaps of earth they may be, yet they do not necessarily stand the tests of time, nor the march of water and wind. Even in elder days, they realised this would be true, and so made arrangements that even after uncountable ages, all would know the place where the Kings of Old still rested.

1 - By the Ring of Standing Stones upon its brow
2 - By the Lonely Dolemn crowning it
3 - By the Bolts of Lightning it calls down from the full moon

9 - By the Weald-Tree that crests it
10 - By the many, many Satellite-Tombs that ring it
11 - By the Tales that still speak the Dead King's Ancient Name
12 - By the Clearly Audible Whispers of the Dead, beckoning you
13 - By the Crows that still feed on the small bones
14 - By the Will-O-the-Wisps that dance and cavort about it
15 - By the Incredible and Improbable Stench
16 - By the River that pours forth from it
17 - By the Frosts that cling to it, even in the Light of the Sun
18 - By the Howling of the Spirits at the Witching Hour
19 - By the Bones that stud it like Weeds
20 - By the Lack of anything Living within a hundred feet of it
