A long time ago there was a herd of.... well, they call themselves Unicorns, and a few of them are -- but really they're horned ponies. Always viewing themselves as better for their horns, the herd found beauty in who they were and ensured they only continued on with those with horns. This was fine, for a time, and while they were viewed often as stuck up they didn't mind. They were happy. That is, until a few generations back, when their reigning leader passed away and a new one was formed. Especially awful in their belief, they began the easy task of separating the herd from society. Creating a false narrative that they should go into hiding to preserve their kind, the leader managed to encourage the herd to rehome into a section of caves deep within Winter's Breath. It was then the ultimate lie occurred several years later; the leader claimed they must remain in hiding for an unforeseen amount of time, for they were the last of their kind. While now you'd be hard pressed to get a definitive answer on what kind of lie they had to spew for the entirety of the herd to remain in the caves for generations, it seems evident the lie they spoke of changed constantly depending on the pony they spoke to. Truthfully, they were a master of their craft, and by the end of their reign they had successfully manipulated the entire herd into hiding for several generations. What did they get out of it? No one is sure, but now we are at current times. The herd has realized they cannot just stay in the caves. The once plentiful mushrooms and cave-dwellers they used to consume are running thin. They are running out of options to breed. Running out of room, most importantly. The cave has begun to produce deadly gas that they can either accept as their fate or, instead, try out the world beyond. These "Unicorns" are coming off a long history of lies, manipulation, and general false information. Not all of them are actually true Unicorns, in fact. These ponies do not know what lays outside the caves anymore, as they were born within the caves and fed stories by those who also were born within. The outside is, at most, a scary story, but some of those within the herd either doubt these tales or are ready to challenge them.
This was how Bokin grew up. She lost her sister to the deadly gas that was filling the caves and her father who was the only other member of her family told her to leave with those who were leaving rather then starve to death. She left with several others of her kind and ventured out into everchange. She was overwhelmed with the world she walked into and at first had a mental breakdown of sorts being unable to cope with the world. She ended up being taken care of by social workers and having to see a therapist. Few could believe what happened to her and fewer still could understand the horror Bokin felt when she learned her life was a lie. She began to pour herself into learning about this world. The good the bad and all the in between. She has become a therapist to help others like herself who were lied to for years.
