Seavil

Seavil is the non-binary ship between Seam and Jevil from the Deltarune fandom.

Canon
Jevil and Seam were once close friends and co-workers. Seam worked as the Court Magician and Jevil worked as the Court Jester. However, one day Jevil encountered a "strange someone", presumed to be the, and went insane. Following this event, Seam was forced by the four Kings to lock Jevil away.

Seam started to see the world more pessimistically after Jevil went crazy. When talked to, Seam explains that Jevil's crazy talk has made them see the world "darker, yet darker" ever since. They became nihilistic. They are willing to let Jevil go free even though the chaos caused by it would be someone of the greatest chaos the land has ever seen, as they believe the end will come sooner or later anyway.

Kris, Susie and Ralsei can find Jevil on the ?????? floor of the Card Castle. If they talk to Jevil, he mentions that Seam knows about the key.

When Kris and their team talk to Seam after meeting Jevil, Seam tells the three about the circumstances behind Jevil's imprisonment. They tell the heroes they can take care of Jevil once and for all. They give the team Broken Key A, as well as a hint of where Broken Key B is located.

If the team talks to Seam after defeating Jevil, the shopkeeper reveals even more about their past and is surprised that the team managed to successfully defeat Jevil.
