From publisher blurb:
The Stars are right… here is… Great Old Ones of Porphyra!
The Great Old Ones are not of Porphyra, for they are alien entities From Beyond, originating in a dimension unknown to thinking beings. According to the Elemental Lords the Great Old Ones appeared in an invasion more than 3000 years ago. The Old Ones claim that this world originally belonged to them and say that the Elemental Lords were the slaves of the Old Ones, slaves who wrongly rebelled and brought about a stunted world, a world where dull matter inhibits free will. The ability of the Great Old Ones to manifest themselves has been changed by history. They have very little power over the elements, for those powers were taken by the Elemental Lords. These and other, subtler changes exist, and expecting Cthulhu on Porphyra to be exactly like Cthulhu on nearby realities can be a fatal mistake. Reality never lies, but mankind is not ready for the truths it can reveal.
A new Purple Duck Games book of religions by Carl Cramer for the Porphyra Roleplaying Game, Great Old Ones of Porphyra contains:
- Details of the religions of eight Great Old Ones – Cthulhu, Dagon, Hastur, Nyarlathotep, Shub-Niggurath, Tsathoggua, Yig, and Yog-Sothoth. These include domains, religious traits, spell preparation rituals, and details on the cult of each one on Porphyra.
- Two new human races from Porphyra's mysterious north, the primitive Sikayans and the urbane Kayanoi, rooted in the history of the Great Old Ones.
- Ten spells with the mythos descriptor to shake your perception of reality.
- Eight mythos tomes expressed as spellbooks, each with spells of all spell levels and a special preparation boon, a power gained for using the book. The books also have a description of contents and bonuses to lore and insidious but interesting curses for avid students. The tomes are the Book of Azathoth, Book of Eibon, Dhol Chants, Necronomicon, Seven Cryptical Books of Hsan, The Curse of Yig, The King in Yellow, and Unspeakable Cults.
