The elves' kingdom is deep in a forest where humans never tread. Elves don't trust outsiders. Most have never seen a human. You, however, dreamt of adventure and leaving the forest. That made you a bit of a social outcast.
You return to the forest after a long hiatus, worried about how you would be treated now that you have human and dwarf friends. To your surprise, you were treated well in all the land.
The elf king even granted you the title of Crown Regent. He's relieved because elves had foretold of the ancient dragon's revival, but laws dictated the king must fight it.
