Kahooli

Kahooli is a god worshipped in Midkemia.

Betrayal at Krondor
The Temple of Kahooli is near Kenting Rush.

A book in the The Vaults at Sarth calls Kahooli the God of Revenge and says he is often misperceived by common folk in the Kingdom of the Isles.

According to Brother Marc, many Nighthawks exclusively worship Kahooli. Occasionally, a near-deathless state is bestowed on Nighthawks who devote themselves to Kahooli, turning them into Black Slayers. A spell called Final Rest, developed with aid from the Temple of Lims-Kragma, can prevent this transformation.

Return to Krondor
As her final gift, Talia turns William into an avatar of the deity for a short time, and he defeats Bear.
