Grthskyn, the multi-headed many-eyed beast who watches always. Its voice echoes thricefold, tone varied and never the same. A scent like old books and damp caverns permeate the air around it. Many eyes watch and watch, observing and piercing.
It is large, it is unnatural, is it even a dragon? Unknown, unsure, the Grthskyn simply stays tucked away in libraries. Hidden amongst books that make no sense, sigils and runes twisting like living things on pages that turn whisper-soft in your claws. A heavy presence prickles at the back of your neck, but you never quite are able to manage a glance at the being that lurks.
Until you do, and then its many eyes seem to lock you into place, whispers bubbling up in your mind until they become a deafening cacophony drowning out your very own thoughts--
Not many escape the Grthskyn unscathed. Fewer escape sane. Be cautious of this beast, this eldritch thing...
