The stories of your homeland tell of a large multispecies kingdom on two islands connected by a single isthmus. Your ancestors left 300 years ago, fleeing a disaster called “the corruption,” but no-one now can determine exactly what it was supposed to be. After months at sea, the refugees found a new land to call home.
Their civilization has had 300 years to grow, and it has become a flourishing republic. Now, it’s thoughts have turned homeward, and it has send a small military force, a small number of settlers and an adventurer’s guild to establish a base of operations back home.
You are a new member of that adventurers’ guild. Chasing stories of your heritage, and the lure of gold, you borrowed 100 gp to pay for your ocean passage, and signed your name to the roster, hoping your unique talents would make you rich in this new, ancient, land.
