Under the Same Moon
Under the Same Moon is a story-heavy GURPS campaign about werewolves. The player characters will be a pack of werewolves living on an alternate timeline Earth in a post-catastrophic area called Calanthis. Fair warning: the campaign will include a fair bit of time travel, so be prepared for your brain to be broken.
Check out the Character Creation page for some preliminary guidelines for building your character. Ask me if you have any questions! GURPS is kind of a convoluted system.
