No Mercenaries, Only Prey names the Talons' place in the wider war: the Ten Thousand hire no swords and seek no truce, and so their only lasting bonds are enmities. This stands throughout the campaign, for the Watch has no peace to offer and none to seek. The Custodes may declare a psyker-reliant war-host their quarry — a seer-council, a witch-cult, a Zoanthrope-brood — and earn bonus Reputation for taking its casters Out of Action. In turn they are hunted by the swarms and tides that out-body the gold, which seize the initiative in scenarios against them. There are no shared rosters here, only predator and prey.

The Emperor's Requisition binds the Talons to an Inquisition retinue — any Ordo, for the Ten Thousand answer the Throne, not one named Inquisitor. The bond opens only in the campaign's later phase, as the war deepens and the Watch consents to second its elite. Its terms are campaign-only: the Custodes lend their throne-elite bodyguard and the Sisters-of-Silence null-maidens onward as a requisition. No Inquisition fighter joins a Custodes gang in an ordinary battle, and no Custodian is remade in another's roster — the lent units are inlined by reference, the same demigods answering elsewhere.
