so here is the first page of Thomas's backstory

I was just explaining here that Thomas had a normal life until sadly his mother passed away due to sickness, so he may still have time for fun but he mostly had to work to help his dad, but this earned him his cute mark witch is packaging and transporting goods, the town was getting bigger because that is bound to happen, but again life was normal

until one-night which will be reviled next time

And yes that is the mare in the moon because this was before Luna came back, of course, at least there is some connection to the show that I want to make because this was way before most ponies we know were ever born.
