After the foundation of the Alyres on IIo, the star Aeras was renamed Yesas and it is believed that the god ruling the star was overthrown. The cult of Aeras believe that Aeras will someday reclaim his throne and cast out Yesas. This cult is outlawed in the Alyres, but even worshipping Yesas is frowned upon since the Sundering of the Seal as the Alyres has moved more towards atheistic tendencies.
