Here are some notes from the Atlantis setting I'm working on.
Lemurian Sorcery
---------------------
All known sorcery is ultimately derived from the lore of the ancient continent of Lemuria, now long lost to a distant sea. Few original examples of Lemurian writing survive, but it's lore has been handed down through the ages and survived in one form or another in various corners of the world. Over the years Atlantean adventurers and traders have brought back a wide variety of documents and artefacts which have accumulated in various royal and private collections.
Sample Lemurian Grimoires
The core of these documents are written in Lemurian script, or some synthesized version of it, annotated and combined with passages in any number of other languages. In addition to magical lore, they also often contain intriguing hints about the nature of Lemurian society, beliefs and practices.
Sorcery (Manual of Slave Management): Hinder, Dominate (Simian*), Sense (Simian*), Palsy, Treat Wounds.
*These spells only affect humans and some higher forms of ape.

*When cast on a lizard it turns into an unknown insectoid creature with four body segments, the middle two of which are winged and the hindmost of which glows with a pulsing blue light. The creature begins to smoke and inevitably dies within a few minutes if the spell is not cancelled.
Sorcery (Tome of the Sticky Tongue): Animate (mud), Abjure (Water), Dominate (Fish), Smother, Project (Taste), Shapechange (Toad) to (Fish).
