Sebastian was going to say no when he stopped to think.
And indeed it wasn't. Grave Whisperers and Quiver Lords were rather rare professions.
The second was grouped with the bow master and the Sharpshooter inside the archer group, or class, or whatever.
While the Bow master mostly had skills that increased attack, damage, penetration and the likes, and while the Sharpshooter had skills that improved the aim, or gave homing effects, the Quiver Lord was completely different, as it was a sort of hybrid between the archer and the elementalist.
Essentially, they could summon arrows with various effects. Stone arrows with incredible penetrating effects, flaming arrows that burned the target, and even some that could generate electricity and stun.
It was a very versatile profession that was used often against beast weak in some elements.
