You could just tell everyone you lost your brows in the calamity... along with your "man parts", and while fleeing for your life, a stray meteor grazed your buttocks.

As for me I would do what Atoll above me said. I'd first try out casting magic... I'm not gonna lie, I will walk outside and blow up an unsuspecting marmot with Flare....
After that, I'd probably get my bearing straight, and then gear up and test my mettle (and pain tolerance) outside. If I can stand the pain, I'll become an adventurer. I may also intentionally injure myself on WHM just so I can watch my injuries instantly seal themselves up with a cure, etc. If I cant stand the pain I'll hole up inside the city walls and become a crafter for hire, because how cool is it to just synthesize something without having to put in all that work sawing and cutting and grinding up materials![]()
