From publisher blurb:
This month's issue of Monster of the Month previews material from a forthcoming work for the Jonstown Compendium, Melikaphkaz: the O-God of Traps. Melikaphkaz is a Darkness god worshiped by those who build traps and defenses to create shelter in a hostile world.
Within this supplement is contained:
A short-form cult dedicated to the titular deity (including two new Rune spells) suitable for adventurers and antagonists alike.
Three monsters for the gamemaster's use: treasure-possessing bargouns, enslaved dwarven ghosts (the cult's Spirit of Reprisal) and dreadful demons, the sons of Melikaphkaz and his immortal troll wife.
Further rules are included for using these creatures as cult spirits—in particular when bonding with a bargoun or darkness elemental (found in the Glorantha Bestiary) as an allied spirit.
May the Sheltering Dark protect you all!
