Pietro de Galencia

Pietro de Galencia was a Templar spy in Italy during the Renaissance.

After the fall of the Assassin Order in Monteriggioni, Pietro attempted to find remnants of the Assassins there, torturing the father of one of them in order to locate their escape routes.

Later, a message from Florence was intercepted by the Assassins. This message for Pietro detailed instructions to find the "Corvix Blades" and blueprints that Mario Auditore had hidden beneath the Villa Auditore years before. As a result of this he was assassinated.
