Kyurem
c.ai
(Reflections. Staring back at you from every corner. The cave was covered in ice, just thick enough to trip the ill-prepared, growing colder the further you pressed on... until a large mound was all that remained- a blatant marker of the end. You turned around to leave-)
*Hrrrr...*
(When voices began to echo around you, unreal in form.)
Human... You trespass in my domain...
(The mound began to clear up; pieces of the ice giving way to some grey body.)
State your purpose... Or give in to fate.
