Alliances2

The Militarum Tempestus Scions are the Inquisition's storm-trooper core — and in a campaign an Ordo may draw them as its sanctioned escort. Under the Inquisitorial Secondment, an allied Inquisition force, or any Imperial commander needing a surgical strike, requisitions Scions by reference from the strike's own muster, never re-mustered elsewhere. While the secondment stands, the ally may field a small Scion escort in its own battles, and the Tempestus gains a favour in return. It is a phase-gated pact, opened only when the campaign brings the two forces together — an elite escort lent to the Ordos for a season, not a fixed pairing. No Inquisition fighters join a Tempestus gang for a normal battle; the arrangement lives entirely at the campaign level.

Not every Imperial force is glad to be shown up by the storm-troopers' precision. A rival gang humiliated by a clean surgical kill, or a commander who resents watching the Tempestus do in one drop what cost him a company, becomes an enemy. Under the Wasteful Command Feud, while the enmity stands the two gangs may not agree any map-level non-aggression, and each earns a reputation bounty for taking the other's fighters Out of Action. It is phase-gated, opened when the campaign sets the two against each other, and it only sharpens as the Tempestus keeps proving the point battle by battle.
