Seam appears friendly and welcoming, but mentions living through many awful things.

Most notably, the kingdom is drowning in despair and the loss of a close friend, Jevil, to something Seam can't quite describe. 

Due to this, Seam has become hopeless and cynical. Seam became so nihilistic despite referring to Jevil's destruction as some of the greatest chaos the land has ever seen, 

Seam is willing to let the party release Jevil from prison, believing the end will come sooner or later, whether they do or not.
