Javier Soto has accepted your offer to help, and has pledged to carry on The Lady Grey’s fight. He will use his political connections to attempt a “peaceful” resolution, but there is never truly peace in the grim dark future.
Peace in this case just means no open warfare between Inquisitors. Instead, as always, the casualties are at the bottom: The Acolytes.
Filus had help to commit his atrocities. The work even now to sway Inquisitors to The Argent Vanguard. They have to be stopped.
