Their are two main types of runes in Harath: Action Runes, and Object Runic. Action Runes are Runes of power, runes of action. The runes of action are the following:
There are many runic objects, each split up into four categories: Meta, Category, Instance, and Sub-Parts.
Meta runes are runes that covers several categories, e.g. animals, minerals, or vegetables.
Category runes are those that fit under a Meta rune, but are classified as the same group, e.g. mammals, gemstones, or trees. Instance runes are instances of a category, e.g. humans, emerald, or oak trees.
Sub-part runes are difficult runes to use, because the mind has a hard time thinking of these sub-systems as a whole. For instance, Mana is hard for the caster to conceptualize.
Please note, that these categories depend entirely upon the mage in question. A mage that is a swordsman may think of “sword” as a category and “Long Sword” as an Instance of the category, while a mage that who is not really interested in swords will think of “Sword” as an instance of a weapon. Using a sub-rune costs 2 penalty points.
