Adriahni - Monster from a dream.

I had a dream last night, and in it I was reading a bestiary from an unknown game... and in that book were the Adriahni. Truly, a monster pulled from a dream. The Adriahni are scavengers and parasites, they feed on carrion when in their adult form... but when the infest a tree and form a colony... watch out. In the pdf there is advice for including them into any game system, from stat suggestions to tactics. Enjoy.
