Sigil: City of Doors

Between the changing of the guards an hour past anti-peak a message written in blue paint appeared under mysterious circumstances on the walls of the prison yard:

The cogs are in motion. They can't keep us locked up forever.
L'appel Revolutionnaire. Hear the call.
DWG


An investigation of the surrounding area immediately after the message was found indicates that there is the slightest trace of an Evocation aura.
