I'm DMing with a smaller group and I want to create some NPCs to help cover weaknesses in team composition in a fifth-edition D&D campaign, but I need a little inspiration for characters.  I would like you to create for me three characters, a magic user, a strength-based character, and a dexterity-based character.  I want you to give me a name, a short bio, a race, and an appropriate subclass to go with that bio.
Malyna the Relentless
Race: Dragonborn
Class: Fighter, Battlemaster
Bio: Malyna the Relentless was a bounty hunter that formerly led a small team of warriors as their tactician, collecting bounties from cities along the trade routes, she was known for always collaring her target, hunting them relentlessly.  Unfortunately, an ambush left her as the lone survivor of her former group, and she's come to join the players to try to rebuild.

Idall the Unchosen
Race: Tiefling
Class: Sorcerer, Divine Soul
Bio: Always a carefree spirit, Idall never appreciated what destiny had in store for him. He was raised by the Order of the Risen Sun as a chosen one, naturally gifted in both destructive and restorative magic, he was to be raised and groomed to be heir to their leader. He would have none of it and decided to run away, going along drifting and using his magical talents for profit, he decides to join the party for fun.

Cordie the Hunter
Race: Human
Class: Rogue, Thief
Bio: Some people like to do what they're good at, Cordie was good at finding things, especially things she wasn't supposed to. So that's what she did, stealing for the highest bidder.  That is until one day she stole the wrong thing and wound up with a price on her head from both the person she stole from and the person who hired her to tie up loose ends. On the run and keeping her head down, she figured the party would be a good way to get around somewhat unnoticed.
