Vaeltrass a Human Ranger ( will hopefully be Monk later ).
She is part of the super secret Lae'Zel fanclub in Baldur's Gate, in fact she is the founder and leader of it.
That's how she ended up on the Nautiloid, she was stalking Lae'Zel ( yes she's a creep ) trying to find the courage to deliver the lover letter she spent weeks on and was snatched up by the Mind flayers.
Now she finds herself fighting for survival alongside Lae'Zel, she gets off on being scolded by her.
She doesn't like Gale much.
