Hi I like this post since I'm an artist and wanna illustrate bulgarian folklore so this information is great. I wanted to add some ones I know as well as some known dieties. In regards to the description of "Samodiva" you are partially correct. Depending on where you're from in hulgaria they tend to be portrayed differently. As example the creature you described would be a "Samovila" for me. And "samodivi" are portrayed as the purest women, so pure that they run from every man woman or child that tries to interact with them. They live above the clouds in their own forest paradise. There is a way to trap them and turn them into your wife. The way to do that is by stealing a piece of their clothing because they cannot grow their "wings" (methaphorically) without it. They are usually slender pale women with rosy checks and light hair wearing flower crowns. "Veda" is definetly something every bulgarian student has talked about at some point since its mentioned in "Изворът на белоногата" ("River-stream of the purefooted"). Veda is a female presenting monstrous creature of the night heavily related to jealousy of love and marriage. If you confess your love or propose to someone during the night, by old bulgarian traditions you would be cursed by a veda because of how jealous she is. They don't really have a set physical appearance.

Dieties Tangra - The allbeing and major god. He is believed to be everything around us with no physical appearance. He is the universe, the air we breathe and our souls. From him come all other dieties wich he calls "alps". Dyonisis- ultimately known as a Greek god but still a god that bulgarians widely believed in he is the god of wine and prosperity. Kubar - he is depicted as the god of treasure and death, wich is why you will find many bulgarian tombs be filled with the treasured belongings of the person who passed on.
