Spoilers: The errand, the contracts, and the duel. No campaign ending.
Sent after the bound daemon
The Shadow and the Blade FAQ of 27 November 2019 says the Nightlord of Clan Eshin sends Deathmaster Snikch to track Tz'arkan, the daemon bound to Malus Darkblade. Snikch leads Clan Eshin. The pack is required. Malus is the Dark Elf lord in the same DLC, and his possession is the subject of The Daemon's Curse, which is Malus's novel rather than an Eshin campaign chapter.
The FAQ's errand is the biography of the pairing. A Clan Eshin campaign in Immortal Empires is not a scripted hunt that ends when Tz'arkan is found. Malus's Hag Graef possession meter is his campaign's use of the daemon. Snikch's use of the same name is the reason the Nightlord gives for sending him. The two systems do not share a progress bar.
Shadowy Dealings and the clans' work
Shadowy Dealings are Clan Eshin's covert actions against other factions. Greater Clan Contracts are work from the other Skaven clans, paid in rewards and in reputation that opens their troops. Pick a contract for the next war, and notice which characters are already away before you count on them for a move. An agent on that work is unavailable while recovering.
Food, ambush, and the Under-City still belong to the wider Skaven campaign. Eshin's addition is the dealing and the contract. The recovery is the constraint: the agent is gone until it ends.
A duellist who leaves when the gap closes
Snikch is a stealth fighter aimed at enemy characters, especially one already hurt or pulled away from a guard. Clanrats occupy the supporting infantry. Stormvermin are the reserve that stops a counter-surround. Eshin Sorcerers bring the Lore of Stealth. The assassination is a timing problem. When the opening closes, the lord page wants him withdrawn rather than left inside a formation.
Queek wants the duel in front of his own army. Snikch wants the character who has already been separated from it. Tretch wants a way out of the battle itself. Three Skaven melee lords, three different uses of a gap. None of that is a page of Malus's chronicle. The Nightlord's order is the FAQ. The contract you accept is the campaign.
