Grenzo

Grenzo is a scheming goblin in the High City of Paliano on the plane of Fiora. Grenzo has a huge frame for a goblin, but always walks hunched over and clutching a staff.

Grenzo used to be the dungeon warden of Palliano. He had created a network of power through his knowledge of the elaborate labyrinth of sewers and drains that riddle the city of Paliano. He has a key to every lock, a blade for every job and not a shred of scruples to go with either. Grenzo's agents swarm the sewers and crawl through the night — mercenary killers and spies, dispatching problems and watching for opportunities to blackmail.

After the elf Selvala killed king Brago, Grenzo released her from the dungeons in a bid to kill the artificer Muzzio. His plan to rid Paliano from Muzzio's artifact creatures backfired when Selvala released the constructs in his tunnels.

When Marchesa became queen, she fired Grenzo as dungeon keeper. Put out on the street, he became the leader of a thieving gang of goblins and often incites mobs to violence. He found an ally in the planeswalker Daretti, who was targeting former colleagues of the Academy for revenge.
