Spoilers: The Council seat, the plagues, and the prophet's different rival. No campaign ending.
He-who-is-tenth
The Skaven roster of 18 August 2017 calls Skrolk one of the Plaguelords, the rulers of Clan Pestilens under Arch-Plaguelord Nurglitch, and he-who-is-tenth on the Council. His magic there is the Lore of Plague. The page gives him no mount. Total War: Warhammer II unlocks him. Queek is the other base-game Skaven lord, and Queek's fame is the duel, not the pox.
Clan Pestilens on the lord page makes infection a campaign tool. It can benefit Skrolk's own armies and settlements while it harms an enemy. The Pestilent Scheme and plague-spreading Under-Cities are that system. Food and recruitment still have to be planned beside the disease. A weakened city can counterattack. The scheme is preparation, not a battle already won.
Plague on the field, and the units of a later pack
Skrolk combines Plague magic with close fighting. The lord page wants the infantry engaged before he is committed into a crowd, and it wants Clanrats and Stormvermin given different jobs so a breakthrough does not pull the whole army onto one target. He is not a weapons-team general. That campaign is Ikit's.
Update 9.0 extended Skrolk's faction effects to Pusbags and the Cauldron of a Thousand Poxes. Those units belong to Thanquol — Lords of the End Times. The free change to his effects and ownership of the new units are separate, which is the distinction already on the lord page. Thanquol himself is a Grey Seer with his own Masterplans. Skrolk remains the Pestilens lord from Warhammer II.
The serpent's war, and a different Skaven
Tehenhauin's FAQ collision is with Ikit Claw, not with a sentence that names Skrolk. The Cult of Sotek still raises the serpent against the ratmen, and Clan Pestilens is the clan whose religion is plague. A player who points the Cult at Skrolk is choosing a war. The 2019 pack's scripted rival is the Chief Warlock.
The roster sentence, the Pestilens campaign, and the Update 9.0 units are Skrolk's account. An Under-City that spreads a plague is the Pestilent Scheme. Temple of the Serpent sends Thanquol after the Prophet of Sotek. That errand is Thanquol's novel and Tehenhauin's name, and the Cult's war on the ratmen is the campaign.
