So after reading all the flavor text about the mighty Archmage (my name for him) who routed the Dragon Lords from the Firelands, beat down the Lord of the Pit , managed to sneak away with some of the Eagle King's precious gems and created the ultimate artefact: The Crown of Command! This guy then proceeded to rule the Land for several centuries before finally dying. But what kind of man was he? What was his reign like? Was he kindly and good or an evil, maniacal despot?
And what if he felt things were better off with him than without? That no one worthy has claimed his Crown? Think about what's happened recently: the Reaper is stalking the Land claiming souls, the Eagle King is hunting for the Crown in order to destroy it and thus destroy the Archmage's legacy, the Draconic Lords have returned, the Ice Queen is threatening to engulf the Land in an eternal winter, the Armies of Light and Dark are on the march and now there's a bloodthirsty Werewolf prowling the Realms. In short things are in Chaos. So what's a deceased Archmage to do? Why return from the grave, of course! And whether he was a nice guy in life or not, he sure isn't this time! He plans on resurrecting himself (perhaps with the help of a cult of followers), reclaiming his Crown and ruling the land of Talisman forever!!
And it's the heroes' job to stop him.
The new board is the NetherRealm (or Land of the Dead or Necropolis or whatever). This is the Realm that the Archmage is trying to climb out of so the heroes need to go in and stop him. It could be a corner board with the entrance at the Graveyard or another overlay for the Inner Region, whichever would work better. With the theme being what it is, obviously most/all of the cards would be based around undead things and the like.
That's about all I got so far. What do you all think?
