In this alternate world of MLP everyone is human ( with exception of certain races like argonians and khjit) , mer ( elf)
,and dovah ( Dragon).
This takes place after TES V: Skyrim,dawnguard,and dragonborn. The last dragonborn has dissapeared after defeating
the first dragonborn now he is back after he is rediscovered 100 years after the defeat of alduin so time period is roughly 4th era 300-302 and with the dragonborn being found new enemies come out from hiding and old friends.
( quick note this verison of dovahkiin is based off of two things my skyrim save file and a roleplay)
