Spell of Silence
This spell guarantees a character cannot speak about a certain subject, reveal certain facts, etc. The spell is automatic when placed upon a character with a Psyche less than the caster's. A successful spell rank FEAT roll is needed if the target's Psyche is equal to or higher than the caster's. It is through the use of this spell (and the Forgetfulness spell) that Doctor Strange has kept the general world unaware of his activities.
