long long a go, after lunas banishment. a group of bat ponies was banished and chased out of town for being followers of nightmare moon.
the poor bat ponies were banished in to the deeper parts of the everfree, tired and very sad from leaving their homes they traveled. deep into the everfree.
upon seeing the poor tired bat ponies while on patrol, Queen rune, the ruler of a nearby hive listened to their plea and felt for them. and made a pact with them. if they gave her their loyalty and only a small bit of love. she would let them stay.
not left with many options the bat ponies agreed to queen rune’s proposition.
rune was a very king and generous changeling queen, she didnt even feed off of much of their love, able to sustain herself and her changelings witht he love of eachother.
from then on batponies and changelings lived i hormony, relying on eachother. deep in the everfree. together they worked on a project of hybrid chngelings. making changelings look more pony like and lovable.
