Infinite light and dark

Planes

The plane of infinite light is an infinite white-hot bath. Within this bath live various spirits. The plane of infinite dark is a total void, possessing no matter and no light.

Spirits

Within both planes you may find various malevolent spirits which respond to light. These spirits in the infinite light are fairly inconsequential, as they rarely notice any spot of darkness. In contrast, the malevolent dark spirits are inevitable blights who will pick up on even the slightest disturbance to their dark home. In both planes there also exist the charitable blind spirits, who may be drawn in by powerful smells. The blind spirits are symbiotic, and may heal wounds, restore sanity, or repair damaged souls. Both kinds of spirit are also receptive to sound, but neither recognize any other senses. In their natural state, malevolent light spirits will hunt down and exterminate any and all dark spirits before attacking other things; the converse applies for the malevolent dark spirits.

Light & dark magic

Light magic

Light users are capable of opening a window to the infinite light, and, naturally, illuminate anything to a great degree.

Spirits

Light users may find employment at a church, wherein rituals are performed, burning incense and applying perfume to draw in blind spirits. Occasionally, a malevolent spirit may cross over instead, which is why churches also usually keep a dark user nearby.

Dark magic

Dark users are capable of opening a window to the infinite dark. They can, but should most certainly not, use this power in the inverse manner to a typical light user, to darken any room.

Spirits

Dark users are trained only to mitigate the consequences of a malevolent light spirit appearing. Malevolent dark spirits are very easy to summon, and as such will wreak havoc on any area. Dark users may still perform healing rituals, but first the room must be made pitch dark, and all parties must remain silent throughout. This ritual may be made safer by implementing dark gems, but again silence must be maintained throughout.

Fire & ice magic

Both fire and ice users tend to be adept at wind manipulation for their ability to create heat or cold in controlled patterns. The main difference is that fire users may stir wind up indefinitely, while ice users will eventually cause the air itself to rain down, if they continually cool it so.

Fire magic

Fire users may engage a siphon between the infinite light and the physical. The most simple realization of this is magical fire, which burns energy from the infinite light. Fire users may also control the flow of water, after extensive training.

Ice magic

Ice users may siphon energy from the physical to the infinite dark. With this, they can contain or lead the motion of fire and wind, as well as freeze anything. While magical ice does not exist, ice users are uniquely able to create liquid or solid air, which quickly boils into breathable air once more.
