Adimonde
The Fiend God
Adimonde grants power to ambitious Fiends, even those who intend to replace him, and feeds on Archfiends betrayed by their successors. Jadzia finds that this pattern has repeated across generations. Adimonde says he too is trapped in a cycle and that, for now, he prefers the strange life of small worlds to consuming everything at once. He uses impersonation and negotiation as well as force. He wagers with the Hero for the right to enter Lore and wins when Nulgath refuses a victory he thinks the Hero arranged.
