Spoilers: Sotek, the collision with Ikit, and the novel's prophet. No campaign ending.
Sacrifices for the serpent
The Prophet and the Warlock FAQ of 4 April 2019 calls Tehenhauin the prophet of Sotek. The Red Crested Skinks follow him, and the FAQ says they sacrifice so the serpent god becomes manifest. He leads the Cult of Sotek in Immortal Empires, and the pack is required. Warhammer II ownership unlocks Mazdamundi and Kroq-Gar instead.
The Prophecy of Sotek is a sequence of objectives. Sacrificial Offerings feed the sacrifices, and they are a different stock from the Spawning Sequence used for Blessed Spawnings. The Invocation of Sotek is the reward that brings an aspect of the serpent into a battle, which is worth saving for a fight the army can follow up. Saurus Warriors can hold. Skink Skirmishers shoot from another direction. He is a Skink caster, so a melee character is what keeps a duellist off him.
A collision course with Clan Skryre
The same FAQ puts the prophet on a collision course with Ikit Claw, arch Warlock Engineer of Clan Skryre, and it says both fight the Vortex. Ikit's Forbidden Workshop and Tehenhauin's sacrifices are the two campaign systems the pack adds. They are not one resource.
Under-Cities, the FAQ says, come to all Skaven legendary lords with that release. The plague-spreading work of Lord Skrolk is a Warhammer II base campaign, not the Chief Warlock's workshop. The Cult of Sotek still treats the ratmen as the enemy the serpent was raised against. Skrolk is the Plaguelord the base game gives that enmity a named general. The pack's named rival is Ikit.
The Prophet of Sotek in Temple of the Serpent
C. L. Werner's Temple of the Serpent is book 2 of Thanquol and Boneripper. The jacket sends Thanquol to Lustria to kill the Prophet of Sotek. Tehenhauin is the prophet of Sotek in the 4 April 2019 FAQ, the Red Crested Skink whose sacrifices are meant to make the serpent manifest. The novel's errand is that killing. The jacket states the mission and leaves the result.
The 28 June 2022 prologue lists Tehenhauin at Xlanzec. That settlement is the prologue's row for the prophet. It is a dated list, as Hexoatl and Itza are. A Cult of Sotek campaign that burns a Skaven under-city is the player's sacrifice war. It is not Temple of the Serpent, and it is not an End Times chapter. Thanquol's other novels are on his own lore page.
