Is a Gamble Worth a Gander?

Orario, city over the dungeon. Adventurers blessed by the gods and goddesses of their familias gather here to make their fortune. A faithful brother has come here to do much the same. A failed blacksmith's apprentice, he turns to the promises of wealth given by the labyrinth deep beneath the city.
Taking up the sword of his great-grandfather, a legendary adventurer who made his name without the blessing of any God, our hero will find there are no easy solutions in life.
