I got down everything except the backstory and how he found the tower; I've got those sections planned out though and I'll get around to adding them soon. For now I figured I'd just show you what I had so far, and gauge your reaction to his weapons.

[hider=My Mostly Complete CS]
[u]Name:[/u] Wizard Crompter

[u]Aliases:[/u] Cromp, Crompy, The Drunkard

[u]Gender:[/u] Male

[u]Race:[/u] Human

[u]Appearance:[/u] Crompter's appearance is not elegant by any means. He looks every bit like your run of the mill pauper, with worn and filthy (but comfortable) clothes, the face of a man down on his luck, and the reek of alcohol so pungent that it can [i]almost[/i] mask how rarely he bathes. He stands at about five and a half feet tall, a few inches shorter than most men. His build is far from puissant as well, for while he is not fat or even flabby he certainly wouldn't be described as muscular either. His hair is unkempt and down to his shoulders, mostly light brown but with a good deal of grey beginning to appear. He has short but scraggly facial that's all grey, and his face is slightly wrinkled. 

Still, through all of that roughness it's easy to see that he was once a handsome and happy youth. Things have changed, though, robbing him of that allure and giving him a weary look. His brown eyes are wizened if you look closely enough, though of course few people do. In any case, for all the intelligence behind those eyes there is an equal amount of apathy, contempt, and cynicism at the world.

Altogether he appears to be in his mid forties, which is incidentally about as old as he actually is. In an age when most men die young, you could call him an elder, though of course his ragged appearance ensures that he receives none of the respect that most his age are able to command. He looks exceptionally young and robust for somebody with his indulgent and depressed lifestyle and temperament, which is most likely due to his magic being capable of slowing down his age.

[u]Backstory:[/u] 

[u]Weapons:[/u] Wizard Crompter always wears a belt, no matter the outfit, and on his belt he keeps two objects: a wand and a small leather pouch. 

The wand's purpose is obvious, being used by many sorcerers to project their magical powers more accurately and easily. Crompter has an especially exquisite one that was crafted from magical wood by elven wood-singers, before being doused in all sorts of strange oils and undergoing various enchantments and imbuements to make it stronger. The result is a rare and effective tool, a remnant from his time as a affluent and prominent members of the Institute.

The pouch that he carries is for a stranger and much more secretive purpose. Inside of it he carries tiny, thumb-sized figurines and dolls made of wood, stone, metal, and all manner of other materials. They would be fine toys for any children, the wildly varied collection sharing the sole trait or being flawlessly crafted with amazing detail and precision. There are savage orcs clutching axes, sly bandits with bows, ferocious bears, and all manner of other things from across the world. While Crompter might keep some as souvenirs, they are certainly not toys. Instead, they are like acorns; tiny seeds that can grow into mighty oaks, or in this case, live monsters and beasts to aid him in combat.

He merely has to open the pouch, toss a few of the figurines onto the ground, and use his magic to grow them to life-size (or bigger) and convert their inanimate composition into flesh and blood. While such a feat is unheard of and considered impossible by the other, narrow-minded and incompetent mages that follow study the art of Alteration, Crompter is in another class entirely. It certainly isn't easy for him to create more than one or two bears or trolls in the thick of combat, and once they are summoned he struggles to control them in even the most basic of ways, but nobody ever sees this trick of his coming. Still, they make a good distraction most of the time. One has to wonder though whether all of those 'toys' stowed in his pouch are just what they seem or if they were once living beings...

[u]How did you find out about the tower?:[/u] 

[u]Personality:[/u] On the surface he is negative beyond belief, a physical and mental drain to anybody within earshot. You could say that his temperament is sarcastic, cynical, mistrusting, spiteful, bitter...the list goes on. Fortunately for the rest of you, he is usually happy to keep mostly to himself and not be the one to engage in any interaction.

Perhaps someone patient and amiable enough (They'd also have to strike him as being a decent person and not a dimwit, of course) could break through his shell and bring out the warm and vibrancy that he once had, but good luck with that.

[u]Magic School and Skill:[/u] Alteration. He has never bothered to learn more than most basic parts of any other schools, and much of the little tidbits that he did learn about those he dismissed as rubbish, impractical, convoluted, or otherwise worthless. That, or he got drunk and forgot about them. In any case, Alteration is about all that he works with, but fortunately he's perhaps the most powerful Alterist in history. Primus himself would have been impressed (or perhaps even surpassed) by Crompter's talent in that one field.[/hider]

Crompter's Alteration magic probably makes him one of the better fighters to begin with because he could shrink you, turn your fancy steel armor into a thick layer of cow dung, or perhaps just be more direct about it and send a blast of magic that turns whatever it hits into stone. I'm hoping that you won't think having his pouch on top of all of that makes him overpowered. I think it's a pretty double-edged sword every time he uses his pouch because it just creates chaos and he has no way of knowing what one of the figurines will do once he revitalizes it.
