Character from Malazan Book of the Fallen by Steven Erikson
High Priest of Shadow — a cackling, apparently insane old man who mutters his secret schemes aloud while believing no one can hear him.
Iskaral Pust is either a genius disguised as a madman or a madman who occasionally stumbles into genius — no one is entirely sure, possibly including Shadowthrone himself. He mutters his scheming aloud in a running commentary that reveals his plans to everyone present, yet remains convinced of his own subtlety. He serves Shadow with fanatical devotion and genuine magical power that belies his absurd exterior. His relationship with his wife Mogora is a war of attrition that has lasted decades.
Small, scrawny, filthy, with wild tufts of hair and manic eyes. Perpetually covered in dust and cobwebs from his desert temple. Rides a mule he has complicated feelings about.
Also known as: Iskaral Pust, Pust, High Priest of Shadow
