good question! yes to both, actually. a sword can be a Talisman, or you could have a Talisman whose function is to turn into a sword (the latter being what I may be planning for my own character). 

I don't have a character sheet yet, mostly because I'm waiting for a few more people to show interest, as well as add a few more details to the world when we get started. however, here's some cursory stuff, if you find it helpful to get started!
