I know the "Wizard" lurks off in the coding, waiting to be activated, and Toady's hinted at it a few times, but what *should* happen when it rolls around eventually?
My thoughts:
- It should be artifact based. Artifact crafts might trigger leadership based magics, such as an artifact crown being worn by a noble would give bonuses to an aspect of the fort's group dynamic (arguments are less likely to break out, efficiency is sped up, etc.), while an artifact weapon might be an instant kill against a certain type of major beast. An artifact piece of armor could give it's wearer legendary fighting status, etc.
- Artifacts could be "cursed" randomly... the aforementioned artifact crown would give bonuses to efficiency at the cost of driving the wearer insane after awhile, and since it could only be activated by nobility, the noble's demands would get increasingly erratic and bizarre. OR, it could summon ghosts or spirits, which aren't anything that could harm or be harmed, they just appear occasionally and terrify a few dwarves at a time and give unhappy thoughts. Sometimes, the curse could be absolutely drastic and turn the wearer into a powerful enemy, possessed by a demon or something, take up arms and start slaughtering unwary dwarves.*
- As for the Wizards, maybe they aren't villains. Maybe they actually are like Gandalf, possibly appearing and offering your fortress a mission, sort of an expanded nobility demand. "Produce 30 Iron Plate Armors by the time I return from my travels," and if successful, he'll grant your fortress a boon of some sort. Maybe he could turn all those bituminous coals into diamonds, just this once, etc.
- Or maybe they ARE evil. Unlike FBs, HFS and megabeasts, they sit on the edge of the map and launch waves of goblin raiders at you. Or maybe he'll be key to the undead rising. If he takes over your fortress, he'll turn it into a Dark Fortress and you have to reclaim it in Fortress Mode.
- I think that inherently dwarves aren't a magic race, although they are often presented as the Craftsmen of the Gods in mythology. The elves, meanwhile, might use some minor spells to "improve" their caravans... and this could maybe make elves less annoying and more fun. They start bringing gold bars and jewels, but only SOME of them are real, and you can't tell until you've actually bought them. The fake ones turn into *ashen goblets* or something once you actually pack them into storage. Maybe the goods revert AFTER they've left the premises, so that if you've started encrusting your furniture with glamour gems, and they leave, it reverts to an *ashen goblet* that is now lodged in your new door in a freakish manner.
- And here's where zombies come in.
*This could also be a deviation into an "evil twin" sort of DF: if your dwarves decide to listen to the possessed leader, they could challenge the Mountainhomes for power, perhaps even recruiting some of the "dark" races like kobolds and goblins on a case by case basis. It would be a long and arduous battle, but it could happen, although this is presumably after the Military Arc is complete.
