He's hoping to get a curse lifted off his family
A young tiefling, Rallio has come to Spellgard hoping to lift a curse placed on his family—a price exacted by his infernal pact. Though deVore entered into the bargain willingly, he has since realized his folly. However, he has been at the monastery for more than six months, and is beginning to despair that he will never see the Sorceress of Spellgard.
Rallio now spends more time drinking in the common room than out in the ruins. Though merely melancholy on his good days, he can turn hostile without warning.
