Rise of Keryvyr

End of the Tenth Seros War
This war destorys the last warring remnants of Hmurrath, though other casualties include an ixitxachitl baron's plan to take over the plateau.

The depths of the Dragonmere off Cormyr become the home to the sea elf kingdom of Naramyr, a former barony of Aryselmalyr.
