Angelic creatures are employees of '''Heaven, Ltd.''', the Angelic [[Factions|faction]].
The etymology of the word ''pterolykos'' is rooted in the [[Languages|Angelic language]], which can be roughly but aptly translated to "Winged companion wolf". As the etymology suggests, pterolykoi resemble white [[wolf|wolves]], but with a pair of angelic wings on the their back, with which they can fly and hover in place.
All pterolykoi have snow-white fur and a pair of brilliant blue eyes. As angelic creatures, they can accumulate Angelic Energy and use certain powers; namely the ''angelic force bolt'', which allows them to fire a bolt of energy from their maws to strike targets with, as well as the ''stun howl'', which is a loud, echoing and fear-inducing howl-like noise that can freeze other creatures in place for a brief moment. People that have been targeted by a stun howl have described being wracked with uncontrollable and paralyzing fear for a few seconds.
Pterolykoi are non-evolving angelic creatures that are unable to speak any kind of [[Languages|language]], and are therefore not considered sapient. However, even though they cannot speak any, Pterolykoi seem to clearly and accurately ''understand'' every word spoken, and provided they come from an angelic that outranks them, or a person they protect or trust, they will respond accurately to requests and orders, no matter which language is being used. Pterolykoi were observed responding to orders spoken in Angelic, Common and Youkai-go, which suggests a level of intelligence on par with sapients.
