The Occuria created auracite from two large crystals called auraliths that contained tremendous amounts of magick, in much the same way they had created nethicite from the Sun-Cryst. The Occuria gave this auracite to Feolthanos, the leader of the aegyl, intending to use him as they had used King Raithwall. Feolthanos enraged the Occuria by refusing to serve them; instead he and the aegyl fled to the sky continent of Lemurés where he used the auraliths to create a barrier around his floating world.
