Saracon

Saracon is a member of The Hidden.

Biography
Saracon cut off his finger, wearing an ancient ring, sending it in an envelope to Malcolm Merlyn. He and his mother sent The Hidden to attack his fortress, killing almost everyone. He sacrificially ate the heart of a llama that had died, while his people breached Malcolm's defences. A day later, Saracon had captured Malcolm Merlyn, putting him in a cave that would eventually flood. He forced him to admit his true name, Arthur King.
