Eric is a follower of the demon Agrith Naar, and is involved in the Shadow of the Storm quest. He is one of the dark wizards recruited by Denath to summon the powerful demon. He wishes to summon Agrith-Naar so everyone in the world will pay attention to him, and that "She" will stop ignoring him. He is eventually killed by rocks falling from a collapsing ceiling shortly after the ritual is completed.
If you break off the dialogue by clicking somewhere else he will shake his fist at you and say "Don't ignore me!".
He may be named after the titular character in the book Eric, in which Eric tries to summon a powerful demon but ends up in a worse situation than he expected.
