The Witcher 3: Wild Hunt - Hearts of Stone

Geralt takes up a contract sent out by a noble named Olgierd von Everec, who tasks him with eliminating a giant toad monster in the sewers of Oxenfurt. While hunting the monster, Geralt runs into Shani, a medic and an old acquaintance of his, whom he has the option of romancing. Geralt then kills the toad monster, only to find it was actually a cursed Ofieri prince. The prince's guards capture Geralt with the intention of executing him. While awaiting his execution en route to Ofier, Geralt is approached by the mysterious Gaunter O'Dimm. O'Dimm helps Geralt escape, but in return, Geralt must help O'Dimm recover a debt from von Everec, who had set up Geralt knowing the toad monster was an Ofieri prince.
