Corin

Corin is a vampire and a member of the Volturi guard, appearing only in the vampire index in the back of Breaking Dawn. Corin is marked as having a special ability, but the nature of this gift is unknown. Corin is also listed as not mated. Corin's gender and appearance both remain unknown; however, given that Corin's name is derived from the latin "Quirinus", it may be speculated that Corin is male.
