The assassin known as Corborin is a lot like an urban legend; both in the deeds attributed to him, and in the way barely anything is actually known about him.
An assassin sent by Val Aregis. At the moment, not much else is known.
He ambushed The Raven Shield on the 23rd of Summersdawn, which left Nova Amaril in a coma.
On the 28th of Summersdawn 642 5E, The Raven Shield planned an ambush of their own, but Corborin managed to flee, either way.
