Larian Studios Forums Baldur's Gate III Baldur's Gate III - General why is Phalar Aluve is a Longsword ?

It's dedicated to the drow god Ellistre (sp?) right? Drow don't have proficiency in longsword. Drow have proficiency in rapier. So why is Phalar Aluve a Longsword instead of a rapier? Don't get me wrong, I prefer the longsword. Just popped into my head a minute ago so I'm curious.
