Murder. Gods. Romance. Musical numbers?!
In a modern fantasy world, college dropout Grace is granted the power of a Muse - power she'll need to find out the truth behind her predecessor's death before time runs out. You'll decide who Grace allies with, who she can trust, and who may betray her in this beautifully hand-illustrated roleplaying musical.
Written by David Gaider, lead writer of the Dragon Age series, Stray Gods is an urban fantasy tale of finding your place, taking charge of your fate, and discovering answers. Your choices will change the endings, as well as the path you take to get there.
