Zyzzathas is a Orsmieri Cave and Dungeon Traveler and a former member of the New Imperialium. He was the son of Raelathas, a member of the Admiralty Board of Cryodiil. Though young, Zyzz became a mechanical genius and was intrigued by Dwemer Ruins.
Inspired by the race of Stonecutters, artisans, and engineers, he dedicated his life to finding the reason the Dwemer disappeared. They invented machines and built elaborate underground cities where they researched powers to rival the gods themselves, but where have they gone? That is the question he wanted answered, and he tried anything to know. Leaving behind only their works and machines, Zyzz utilized and improved upon them to aid upon his excavation.
Zyzz excavated many different Dwemer Ruins, ranging from Vvardenfell, Hammerfell and even the province of Skyrim. He resided inside Nchuand-Zel, where he unearthed a large spider, which he gave her the name of Nimhe.
