You need to submit the character to my game for me to see it.
I think Oubliette isn't a good choice, the game is going to be basically "mundane". No real "magic" being thrown around. Something like Armory, Infirmary, Workfhop, Panic Room, or even a Library would work.
Flame Thrower huh? That's pretty intense.. lol
Magnum is probably easier to carry unobtrusively than a sword and you probably want one weapon that you can carry more easily than a flamethrower. lolz Plus, if Amanda is Chosen she is likely to have something like a sword/axe or the like.
