Vyndara's last name is Manaheart, but she refuses to use it outside of official paperwork for various reasons, the biggest being that having no magical talent and a mage's last name is embarrassing.
Other than that until I can grab her RP profile, here's a fun bullet list:
• Vyndara is asexual and aromantic.
• She's an alcoholic, and somewhat aware of it, but doesn't give enough fucks to bother doing anything about it most of the time.
• Flunked out of Blood Knight training as a young adult, went on to become a regular soldier.
• Probably cares more about her hippogryph steed than anything else on Azeroth. Despite being crappy at a vast array of things, she takes pretty flawless care of him.
