"Seam appears friendly and welcoming but mentions living through many awful things, notably the kingdom drowning in despair and the loss of close friend Jevil to something Seam can't quite describe. Due to this Seam has become hopeless and cynical. So nihilistic has Seam become that 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." (Seam, WIKI)

Although he doesn't have a text-tone reference, his voice would probably be an older, tired voice. A voice of a person who has seen a lot in his lifetime.

"The name’s Seam. Pronounced “Shawm.” Is an awkward line, I know. XD Just be fun with it!
