As the krovlin invasion continues on teras, I wonder that should a half-krovlin be in the room when the krovlin spit out their gutteral tongue would a half-krovlin PC be able to understand?
I always veiwed Krolgeh as a "lower" tongue of the Krolvin language, which obviously anyone can learn.
The Krolvin language option that Half-Krol get to use, I see as being a "high" Krolvin language that would be virtually impossible for anyone not of the Blood to learn and speak.
