From publisher blurb:
This month's issue of Monster of the Month continues the series of Rune Masters begun last month. Inside, you'll find a terrifying Sword of Humakt, Renharth Blackveins. Raised under the rule of the Lunar invaders, Renharth embodies patriotism without hatred, antagonism with respect. In addition to describing Renharth, this issue includes:
Gamemaster advice for using this new Rune Master, including adventure seeds to inspire immediate play
Several cult spirits Renharth has bound, including the Nightmare of the Inevitable Path, which threatens all who see it with visions of their death
A new subcult, Humakt Indomitable, suitable for adventurers and antagonists alike
Two additional non-player characters, and directions for Renharth's retinue in war and peace
Although most of this supplement is usable with the core rulebook alone, you’ll need a copy of The Red Book of Magic from Chaosium in order to use the new subcult included herein.
