At some point, the Silver Griffin received a letter from his fellow member, Machaon, requesting the Griffin to send Deimos to deal with a problem called Klitos.
When the slaves took up arms against their oppressors at the silver mines of Attika, their overseer managed the rebellion so that it grew violent and bloody enough to be used to scare others into obedience, but still could be swiftly snuffed out. As a thank you for this, the Silver Griffin sent the overseer a piece of armor, as well as an invitation to come to the Silver Griffin's abode on the Prasonisia Island, alone.
Instead of the overseer, it was the SpartanmisthiosKassandra who came, slaying the Silver Griffin and his guards, and freeing their prisoners.
Regarded as a unique man for his ability to compel others to his cruel bidding, the Silver Griffin considered himself a teacher, teaching slavers control and slaves submission.
