Chainlink Backstories

This is a story pertaining to a series of roleplays I have going with my friends.
It will be going into much detail about two of my respective characters:

The Silver Songbird is a mercenary - to keep it short and simple. She started off elsewhere as a military general, but now works as a mercenary in different territories.

Kaidrin is a younger teen who was taken by a guild for one reason - his brilliant, brown wings. He learned to adapt to the world he was living in, still holding his bright and joyous nature despite the conditions he was living under.

The story will be delving into backstory between both of the characters, explaining how they got where they are now.
