King Enki was the king of the dwarves. The dwarves of the Black Swan check in with him, and he knows who they are. However, the elves can't force King Enki to reveal the names of the dwarves, because, technically, they are working peacefully with the elves, only, the elves they are working with are in the Black Swan. He attended the Peace Summit.
King Enki supports the Black Swan but is not necessarily against the Councillors. He lets the group use Alluveterre (formerly, before compromised), an underground cavern containing a thriving forest. He is also the one who provided the group with magsidian to light leap out of Exile.
In Legacy, he reveals that he made a deal with the Neverseen and assisted with Lady Gisela's procedure performed on Keefe. He is sent to Exile, specifically the Somnatorium, for his crimes. Nubiti was chosen as the Queen in his place.
King Enki, like other dwarves, has a pointy face and nose. He is also bald because the dwarves, a very hairy species, consider it a show of strength for their leader to wax himself bald. His skin is a mottled mix of brown and grey.
