Greetings!
Well, I suppose I must present a brief list of some of the influences in my campaign. I think the flavour is some rich blending of them all.

To wit--
(1) Tolkein: Elves, Dwarves, ancient history, and dark powers all feature prominently.
(2) Conan: The various human kingdoms and the rough countryside have ferocious monsters, ancient magic, and greedy, grasping tyrants as well as beautiful, cunning women.
(3) Karl Wagner's Kane Series: There are similar barbarian heroes here as in Conan; also there are areas of mystery and bizarre technolgy and ancient malevolent gods.
(4) Jack Whyte's Camulod Chronicles: The attention to detail, grand ancient glories, and twisting plots are all mixed in.
(5) David Gemmel's Waylander series, and Drennai works: Mysterious demons, witches, and lethal assassins are all present.
(6) Michael Moorcock's themes of Chaos and Law struggling, with the ruins of many ancient empires and new ones on the rise.
(7) George R.R. Martin's works involving complex political themes and brutal life and death.
(8) Warhammer Fantasy Roleplay--this blends the juggernaut of Chaos with rennaissance-inspired technology and the Inquisition. These themes are richly woven into the campaign.
(9) Ancient History--the chronicles of Alexander The Great, the Roman Empire; The Byzantine Empire, as well as Egypt of the Pharoes and the rich mercantile kingdoms of the Pheonicians and Classical Greece, as well as large amounts of Old Europe, Persian, Babylonian, Hittites, and other Biblical elements and themes are used.
(10) The Arthurian Tales; and the heroic age of the Celts are heavily integrated in different areas of the campaign.
Well, take all of that, blend carefully in various ways, and that is probably the flavour!
Semper Fidelis,
SHARK
