Also a little bit of a breakdown....

[i]This Force was discovered by four races: the ehki, rakir, lazeruzi, and uburu. Each of these would hold on to the runes of which they held (ehki with harmony, rakir with light, lazeruzi with chaos, and uburu with darkness). The danger of these runes is that they overwhelming of power and domination of their nature. [/i]

Chaos Magic is a sort of red colored generic energy, it is innately corrupting as mentioned outside of the race that FOUND the rune of chaos. So other races that aren't the Lazeruzi will feel a sort of sickly radiation when they are attacked or near an abudnance of chaos energy. Harmony is more-or-less the same in the opposite field (blue colored generic energy).

Holy and Dark magic are sort of malleable multi-purpose curses and blessings (as well as summons, divine/demonic magic, etc) that are colored white and black respectively. They have the same radiative effect, etc etc.

However this is not to say there havent been chaos/harmony/dark/holy users of different races/cultures-- but it slowly corrupts or "enlightens" them depending on the frequency of use; changing their mental state and even their personality. For example in one RP, a mercenary named Marlux got a hold of a chaos artifact he began to use and his brain over-time gave in to impulses, hunger for chaotic results and actions, and ultimately made him insane.
