A Daemonic Siren is imprisoned in this banner, its seductive song lulling the senses of all who hear it.
If an enemy unit charged by a unit carrying the Siren Standard wishes to Flee (or Fire & Flee) as a charge reaction, it must first make a Leadership test. If this test is passed, the unit may Flee (or Fire & Flee). However, if this test is failed, the unit must Hold.
