Phantasmagoria

From publisher blurb:

This is a supplement for Warlock!, the old-school roleplaying game inspired by the early days of British tabletop gaming.

I, Dolkepper the master magician, have collected here what the manticore Strix told me of the creatures of the Kingdom. Some of these beings I know exist, some I have never heard of, and some I fear the beast created for my amusement and to ensure the Rebeck brandy kept flowing. I leave it to you, reader, to discern the truth and identify real monsters from fictions dreamt up by my strange companion.
In this book you will find over fifty creatures that may or may not exist in your game of Warlock, from aerial hunters to wyrms...
