Spoilers: The brothers’ roles in the Lords of the End Times pack; no novel outcome.

Who they are in Total War
The Glottkin lead the Host of the Triplets for the Warriors of Chaos. They are a paid lord in Lords of the End Times, sold on their own or in the bundle, and the purchase is separate from Tamurkhan – Thrones of Decay. Gutrot Spume is the legendary hero bundled with them. The overview also lists Morbidex Twiceborn, Bloab Rotspawned, and Orghotts Daemonspew among the Nurgle characters that pack brings to the roster, and Putrid Blightkings as the new mortal infantry.
In battle they are one model with three jobs. Ghurk is the vast spawn. Otto fights with a scythe from his brother's shoulders. Ethrac is the sorcerer. The overview calls them mighty champions of Chaos, marked by Nurgle, able to command warriors and daemons and to carry the plague god's gifts past the Empire and beyond. That is the game's framing for a Lords of the End Times lord. It is not a scene-by-scene account of a novel.
Gifts, gardens, and a heavier daemonic share
Corruption and souls buy Gifts of Nurgle: rituals of decay and blessings that land on the faction, on characters, or on settlements. The triplets also leave Nurgle corruption in the land they cross. Conquered settlements can become Gardens of Corruption, and those gardens are the gate. They give this faction a higher share of daemonic Nurgle units than any other Warriors of Chaos army, and they generate plagues the host can spread.
Festus brews as a single doctor inside a mortal warband. Ku'gath works the plague cauldron as a greater daemon. The Glottkin's distinction is the garden and the three-part body. A player who wants Blightkings and daemons in the same Warriors army is in their campaign. A player who wants chieftains and a maggot-host is in Tamurkhan's Thrones of Decay, a separate purchase.
End Times as a pack title
The August 2026 overview places the Glottkin inside a download about the End Times, beside Nagash, Thanquol, and Boris Todbringer, with a free update that also reworks Archaon. Their campaign systems are Gifts and Gardens. The short-victory button that lets Archaon stop conquering and raze in the name of the End Times is Archaon's system, described on his page.
Update 9.0 names the Glottkin on Archaon's subjugation list, next to the other Warriors lords. A defeat can move the brothers into his faction and pass their settlements to him, because the Host of the Triplets is already Warriors of Chaos. That recruitment rule is a campaign button. It is not a narration of the defence of Altdorf.
