350pc: The Library Keeper

The Library Keeper is a magical fantasy of wizardly concoctions. A dragon nestled on a couch appears seemingly harmless until it finishes its incantation from the spell book, which begins casting rainbow coloured light to fill the room. Did the dragon act because he caught warning of something when peering through his telescope pointed outside the window? Even with all the candles and candelabras lit bright, there isn't enough information to shed light on this mystery!
