Toria is an Erosion dragon.  As an official Courtesan, Toria chose the shape of an Enxiryixx as her secondary form.  In her official position she negotiates between the Enxiryixx and the people of the surface.

Before being revealed as an Erosion, Toria was first encountered in her enxiryixx form and was known as The Mysterious Arachnid.  She was observed talking with a group that had traveled to Northern Dreamsong to investigate the earthquakes which had begun displacing the Enxiryixx and other creatures from their home territories.
