It is? I've been questing with at least 5 Belves and never had a quest involving it. Ever.
It's one of the paladin quests. The mount one, if I recall correctly.
You don't even need to do that anymore.
I know. But still, it's a class quest. Seems in bad taste to use that spot.
I think it's even removed on retail.
Actually, it's atill there. One has the option to do it, but it isn't essential to getting the mount.
