Appendix I
History and Practice of the Triske StonesThe Firaithi use an array of three Triske stones for divination. The stones are made from spinel[28], a naturally occurring mineral, often ruby red in color, that fractures naturally into a perfect octahedral shape. The three stones are called Moonstone, Redestone and Gyrestone. Each has its own set of four symbols, repeated twice on the eight faces of the octahedron. The history of the Triske is largely unknown, although it is believed to be the oldest and most accurate of all the mantologies of Yrth. It is surmised that the Firaithi originally came from the mountainous east of Yr — the only location where spinel stones naturally occur, and brought lithomancy with them when they migrated westwards.
