I have three types of magic in my world, this unnamed type, spiritual and arcane. All magic types can be used exclusively to create magic.
For this emotional magic it would generate from any heightened emotions but can positively or negatively affect the other types of magic. This energy can also be generated in others that are the driving cause of a high emotional state in another although negative emotions generate more.
Because of these things this magic type is notoriously used and relied upon by demons and is the driving influence in them being 'evil' although not all demons are evil.
For additional (but undetailed) information, arcane uses mana which is passively generated from souls and there's spiritual which is generated with worship and/or a combination of fear and respect.
[Edit 2: The magic types' particular magic energy will be refereed to as spiritual energy and arcane energy or similar.]
With this in mind I don't want to call this magic 'demonic' magic as it isn't even remotely exclusive to them (and would be attributed to magic of demonic design). Neither do I want to call this 'chaos' magic as I don't really feel it fits.
I especially do not wish to unify my magic types as I prefer them to be considered three separate systems that merely interact with each other to produce more complex results.
Edit: I need to add That I can't change it to dark or black, as I would also change spiritual to light (though they don't seem to theme that well with how they work) , because of my elements. These are Earth, Lightning, Air, Water, Fire, Frost, Light and Dark.
Apologies if this is in the wrong place.
