From Stone and Sky
A coven of six immortal creatures, who have always existed. They constructed the world of Stone, the inverted world which is based around the memory rods. These memory rods store all the memories which have ever existed, and span across the turning of the world. This world changing event marks the change of power, for example, from the power of metal to the power of charm, to the power of man.
The basilisk tired of life, and sought immortal death. The six found release, but as they died, the last basilisk had its immortality stolen by Archan, the greatest of the old dragons. With the memories and power of the six basilisks, and driven by evil, Archan now seeks to destroy the universe.
