This is my new oc, Misty Eyes! She is the daughter of Bright Eyes from my little pony tales. After an accident, she was scattered across all time and space, but is still alive and is now immortal. She can visit any time period and any alternate universe by concentrating herself hard enough.
Her accdent was also the cause of g 1.5 going into g2 and then g3 and so on. The events of g2 are not well doucmented but it lead to g3, an era of: technological stagnation, some magic growth and, the three main pony races separating and makeing there own kingdoms to the point that they had forgoten that eachother existed.
When they did rediscover eachother, despite friendliness at first, it soon turned bitter and cold. So cold that it caused windigos to awaken and cover the land in snow. This snow and cold destroyed most remaining technology from the g3 era. This leads into the events shown in hearth’s warming eve and is the start of g4. From there time progresses to g5 where we are now.
