navigation, search © Fantasy Flight Games  Shade of the evening
is a thick, blue liquid made from the leaves of trees that sit
outside the House of the Undying in Qarth.[1] The trees are
black-barked with inky blue leaves.    It is a sorcerous drink
drunk by those who enter the House of the Undying and the
warlocks of Qarth, so that they may "hear and see the truths"
that will be laid before them. It does not turn lips blue with
just one dose; many must be taken.  It smells like rotted flesh
and has a thick oily texture and tastes like all the tastes a
person has ever tasted, and some that a person hasn't. [2] To
Victarion Greyjoy it looks like strange black wine that flows as
thick as honey when poured. [3] When he sees it up close it
looks more blue than black. Travelling warlocks have been known
to take a cask of shade of the evening with them.  There is a
potent magical elixir made of virgin’s milk and shade of the
evening sold at the Port of Qar
