The Harnic Astrology program takes a fully functional and richly detailed Earth-based Astrology Program ("SymSolon") (GNU) and changes the parameters to produce output appropriate for the Harnic Isles and the planet (solar system) of Kethira.
Every GM tweaks the base rules to suit their own style, and that of their players; this is the legendary DongMaster's second edition of his house rules.
