Bitter Taste of Betrayal

Spend enough time in Hell Harbor, and you pick up the paranoia encouraged by Arronax Endymion. Maybe you served under him on the Tyrannous, escaped his executioners, or had a friend who wasn't so lucky; whatever the reason, you have some of his wariness. Unless you're a willing target, you gain a +2 circumstance bonus to AC and saves against creatures you consider an ally and creatures who are undetected by you. If a creature you thought was an ally reveals itself as an enemy, you get the same bonus against them until the end of your next turn.
