Christian Lazaro had made a fantastic 'Four Horsemen of the Apocalypse' build set, though I think that it could be improvized with a little umph to make it all the more fun, with just about the same idea...
The Four Horsemen of the Apocalypse
(There's a purpose behind the colored word: Four...)
War, Death, Famine, and Pestilence.
The First Horseman; Pestilence
Race: Wood Elf
Alignment: Lawful/Neutral
Factions: Dark Brotherhood, College of Winterhold.
Major Skills: Archery, One Handed
Minor Skills: Alchemy, Light Armor, Illusion, Smithing
Perks: Max out Archery, generously apply points into One Handed (not too many...). Max out Alchemy, and Light Armor... rest is up to you.
Guardian Stone: Serpent
Shouts: Marked for Death, Whirlwind Sprint
Equipment: Dragonbone Bow, Dragonbone Armor, Gauntlets, Boots. Jagged Crown. Dragonbone Daggers.
Obs.: His speed and cunning are matched only by that of his plague. What is his plague? Any disease... Insanity, hallucination (forcing others to attack their allies), and ultimately pain. He dares not stand still, and is always on the move... Good luck keeping up with his role in the Apocalypse. The recomended color for the horse is: Pale.
The Second Horseman; War
Race: Nord
Alignment: Chaotic/Evil
Factions: Companions, Imperial Legion, Dark Brotherhood.
Major Skills: Two Handed, Heavy Armor
Minor Skills: Speech, Smithing
Perks: Max out Two Handed - specialize in swords, Max out Heavy Armor. Max out Speech - this is vital. Max out Smithing (Heavy armors side).
Guardian Stone: Lady Stone
Shouts: Unrelenting Force, Whirlwind Sprint, Dismay, Elemental Fury, Fire Breath, Slow Time.
Equipment: Dragonbone armor set full. Daedric Greatsword.
Obs: War... No peace... No rest... War is unrelenting in cruelty in battle - none match his martial skills. His sword is his ally, and his foe is peace - his job is to eradicate any trace of peace; to delve the world into chaos. The recommended color for the horse is: Red (Just use Shadowmere)
Stat placement ratio: 1:3:2
The Third Horseman: Famine
Race: Dark Elf
Alignment: Chaotic/Evil
Factions: Thieves Guild, Dark Brotherhood.
Major Skills: Illusion, Speech.
Minor Skills: Alchemy, Sneak
Perks: Max out Illusion and Speech, max out Alchemy, and Sneak.
Guardian Stone: Shadow Stone
Shouts: Drain Vitality, Whirlwind Sprint.
Equipment: Ebony Mail, Ebony Boots, Guilded Gauntlets, Helmet of your choice, or no helmet at all...
Obs.: The decay of all tangible food other than alcoholic drinks... Famine's job is to steal what food he can and hide it (obviously Skyrim-ized...). The recommended horse color for the horse is: Black (still, use Shadowmere...)
The Final Horseman: Death
Race: Skinny, gangly, High Elf
Alignment: Chaotic/Evil... Wants to kill all Humans
Factions: Dark Brotherhood, anything associated with death.
Major Skills: One Handed, Light Armor(Or Heavy Armor), Destruction
Minor Skills: Alchemy, Speech, Alteration
Perks: Max out One Handed - fill in the axe specialization, fill Light Armor(Or Heavy Armor if you decided to go that way...), Fill Destruction ( only fill in the Ice branch, no Lightning/fire...). Fill Alchemy, and Speech as you see fit, fill Alteration up main branch, to Atronach.
Guardian Stone: Ritual Stone
Shouts: Soul Tear, Marked for Death, Drain Vitality, Whirlwind Sprint, Unrelenting Force, Dismay, Elemental Fury, Slow Time, Animal Allegiance, Kynes Peace.
Equipment: Daedric would seem to match the best... but whatever armor set looks most death-y to you. I mimicked the Equipment i used in my 'The Champion' build. Up to you. Dual wield your favorite One Handed weapon , and kick some royal buttooty.
Obs.: Death... the final phase of the Apocalypse.
And so the four horsemen have been corporealized into Skyrim (I made a separate profile for each Horseman, and killed to get to the phase that that horseman was at... it's really fun to R.P.).
Recommended horse color: Polka-dotted white/black horse. **IMPORTANT**: NEVER USE FIRE SPELLS...
I hope this is even a match for comparison to Christian Lazaro's form of the Four Horsemen... Have fun
-- P.S. I personally love the Death build I had made... R.P. styles match that of what Christian Lazaro had posted in each 'Obs.:' section.
