Polozius was an elven ambassador of the Elven Lands to the Empire of Blood. He did not seem very happy to be there. He also did not seem to like Vaarsuvius for reasons unknown, as Blackwing noticed, and further evidenced by the fact that Polozius seemed to be glaring at Vaarsuvius. It was later revealed that he was in fact Zz'dtri in disguise. Whether a real Polozius exists whose identity Zz'dtri had assumed is unknown.
