Background
The Loyal Servant of Arthur is Good's rank and file: no special ability, no hidden knowledge, nothing but honest eyes and a seat at the table. The Minions of Mordred woke up knowing exactly who you are; you woke up knowing nothing at all.
Don't mistake plainness for weakness. Precisely because you have no information to protect, you can speak freely, accuse boldly, and volunteer for any quest without endangering a secret. The Cleric must guard what they know and Evil must guard what they are — you alone have nothing to hide, and honesty wielded loudly is its own kind of power.
