Leader of The Arcanists (ARC)
Member of Magrathea
Works include The Spiral and The Arcane University.
Ex-Post-Phsyical entity that used to reside in The End, but subsequently returned to the world due to an interest in music and being awesome.
His return to the earth has the consequence of creating a large hole in the ground, which, after building work by Thorowin himself, became Crown Cavern; above which rests The Spiral.
Having retained a link to Post-physical world, Thorowin has retained various strange powers, and so he became the first Arcanist of the Silver Server.
