Ally Who Lied From the Start

The party trusts this ally, and they've been hiding one big truth since session one. This gives you the lie, the real events, the NPC's own justification, two behavioural cracks the players might have clocked, and a scene that forces the reveal. Built so the betrayal feels earned rather than a cheap twist out of nowhere.

I have an ally NPC called {ALLY_NAME} who the party trusts. They have been concealing one significant truth since the campaign began. I need the lie to feel earned when revealed, not cheap. Give me: the specific lie they have been telling, the true version of events, their internal justification for the deception, two behavioural cracks the players might have noticed, and a scene trigger that could force the reveal. Ally name and role in the party: {ALLY_NAME}. How long the party has known them: {RELATIONSHIP_LENGTH}. What the party believes about their loyalty: {PARTY_BELIEF}. Stakes if the truth comes out: {STAKES}.
