Austras Koks – (Tree of the East or Tree of the Dawn) is a fast growing tree. It sprouts at sunrise, and and looses all its leaves after sunset. It resembles an oak tree with metallic silver leaves, copper roots and gold branches. Originating on the shores of the Daugava River (Kurzeme), Vidzeme or Latgale, it is now widely cultivated.
Every part of the tree is used to imbue potions with the power and glimmer of the sun. It is not toxic, and it often added to colas and mixed drinks to make them glow.
