Angels

Angels are some of the most complicated Entities that the The Various Organizations have encountered. Their numbers, what dimension they're from, or even what they are is currently unknown. 
Angels can exist in any form, from a human to a ball of lightning to the very air which we breath.
Regardless, they all have seem to have one thing in common: they want to help Mankind. However, they are extremely elusive and prefer to be "lone wolves" when it comes to helping The Various Organizations.Although at times,they have come together with mankind to save it without the humans actually knowing of their aid or intervention most of the times.
It is thought that they've averted the destruction of human civilization hundreds of times throughout history. 
==Difference between Angels and other benevolent entities==
While there is no definite line between what consitutes an Angel versus a benevolent entity, there is an odd factor: No entity can plainly state that it is an Angel without actually being an Angel, and no Angel can lie. It is unknown why this is, how it is enforced, or who enforces it. Entities, when forced to lie about being Angels, simply self-destruct, as if truly incapable of doing so.
All Angels are very powerful, with Threat Levels of Very High or higher. Unlike Changelings, however, humans do not feel uneasy around them and are even comforted by their presence in a almost soothing sort of way.
