"Built on a massive plateau, Varetta has stood since
time immemorial. Great stone dragons writhe along the battlements, their coiled tails entangling the gatehouses
and portals of the outer wall, and spirals of smoke rise
from the mouths of angry-faced gargoyles, crouching
like spies on top of the roofs and towers that fill the
sky." - Joe Dever
