the Official Monster Scale Guide for Bookahs
A couple of days ago /u/Chiorydax made a funny post "comparing" the size of Zaithan and the Mouth of Mordremoth.
Of course I thought: why not do this for real? And why not crank it up a notch and include even more monsters? The end result: the Scale Guide for Bookahs (or: comparing big things to Kasmeer Meade)
