The Hero sought to enter Ivor Tower Castle to confront Camellia's evil twin, but the entrance over the Chessboard was guarded. Tinker suggested that the hero seek aid from Gomi. At Gomi Tower, the hero fought with one of Gomi's dragon friends, Sterling, but Gomi intervened before either of them got hurt too badly. Gomi agreed to help, and had Sterling fly the hero to Ivor Tower Sewers so he could sneak up from under the castle.
In the ending, Tinker takes Gomi flying on the Windwalker.
Gomi gives the player the Lightning Storm alchemy.
