Patron of cleverness and trickery, Korotiku is an ancient and powerful immortal most greatly revered in the Pearl Islands and Tangor where he is often called The Spider. Clever fighters and rogues revere him, and often his black clad clerics take several levels in one or both of these other classes. Priests utilise tricks and pranks to make people think about everything as much as possible; his mythology abounds in pranks and mischief perpetrated against other Immortals. His followers are close allies of Asterius and Eiryndul and fervent enemies of Loki (who represents mischief done for destructive and harmful purposes).
