Spoilers: Hell Pit, Ariel's magic as the pack's story, and the laboratory. No campaign ending.
One of the nine
The Twisted and the Twilight FAQ of 19 November 2020 calls Throt the Master Mutator of Clan Moulder and one of the nine Lords of Hell Pit. He believes, in that FAQ, that consuming Ariel's magic can save him from starvation. The Sisters of Twilight are the lords set against him. The pack is required for Clan Moulder in Immortal Empires. The belief about Ariel is the Warhammer II story of the pack. An Immortal Empires campaign is not that story's ending, and it is not a Wood Elf ritual result.
The Sisters' lore is the Wood Elf page for Naestra, Arahan, and the Forge of Daith. Throt's side of the same FAQ is the hunger and the laboratory. They share a DLC window. They do not share a campaign system. Flesh Laboratory mutations do not move onto the Forge.
Mutations with a purpose
The Flesh Laboratory applies augmentations, and the lord page is plain that a repeated experiment can leave the subject unstable. Recycling a failed creation returns materials. The useful order is to decide whether the unit needs to reach a fight, hold one, or support a monster before another mutation is stacked on it. A dependable infantry line is what remains when an experiment fails.
Throt fights as a monster handler, not as a caster. Creature-Killer is the weapon the lord page ties to capturing beasts. Clanrats occupy enemy infantry. The monsters attack from another direction. Stormvermin are the heavier guard. Pushing every large body through one gap is how the enemy surrounds them together. He stays near the engagement. He does not replace the line.
Stormfiends, and the pack's opponent
Update 9.0 allows the Flesh Laboratory to put monster mutations on Stormfiends, and it extends Throt's lord effects and his unique skill line to those units. Stormfiends come from Thanquol — Lords of the End Times. The interaction needs both the laboratory and those units. Ikit's workshop upgrades are a different clan's arsenal. Skrolk's Update 9.0 change was to plague units, not to the vat.
The nine Lords of Hell Pit are the FAQ's count, used as the article's wording, not as a list of playable lords. Throt is the one the pack fields. The starvation he means to cure with Ariel's magic stays inside that 2020 story. A mutation you accept in the laboratory is the Moulder campaign. The Sisters remain the opposing lords of the FAQ, on their own page.
