Ilkas Veridun

lkas Veridun, Chui'lana or Ilithic for "Mirror Lake", is sacred to the Elven people. The lake's reflecting surface is incredibly calm, with barely a ripple anywhere. In the center of Ilkas Veridun is the sacred island, Ailaeteorn, home to a giant Sana'ati tree. Ilkas Veridun is just west of Leth Deriel, and can be viewed from the eastern-most room of Tamsine's Rest.
From the Tamsine's Rest viewpoint, one also is reminded of this legend:

Legend holds that the waters of the lake, when used by one of pure heart and spirit, can raise the dead.
