From publisher blurb: Have you ever wanted to summon up space-demons from the moon? Well, now you can. The Blue Book gives you all the information you will need to formulate your own spellbook - your own summoned minions and your own QLPTH from which to command demon armies. Not for those who do not dare blasphemy in pursuit of Power - the Blue Book includes 5 Monster Templates & 8 New Demons - for your reckless wizard to summon.
