Maggoth Lords
The Maggoth Lords or the Maggot Riders are the three Chaos Champions of Nurgle, Orghotts Daemonspew, Bloab Rotspawned, and Morbidex Twiceborn, introduced in the second End Times book. The three of them ruled over Icehorn Peak, a realm located in the Chaos Wastes. They survived the transition to Age of Sigmar alongside The Glottkin and Gutrot Spume.
Orghotts Daemonspew
The leader of the group, and the de facto ruler of Icehorn Peak. Distinguishing him from other chaos characters, he's half-daemon, having been born from the union of a Great Unclean One and a human witch (don't think how that would work for the sake of your sanity). He's also old as fuck, having been alive before his companions and having participated in the Battle of Kislev's Gates during the Great War Against Chaos.
The fact that he's only half daemon angers him to no end, as he wishes to become a true daemon and obtain what he perceives to be his rightful heritage. He's tried many things to become a daemon, from literally walking to the Garden of Nurgle, which was always just out reach for him, and it was during one of these journeys he aquired his Rotaxes, to attempting to contract Nurgle's Rot so that he could at least turn into a Plaguebearer, but to no awail. Since then he's been trying to prove himself to Nurgle and become a Daemon Prince.
He died when Karl Franz ascended, being burnt to ash by the magic of the Incarnate of Heavens.
