I said, "If it was in a revamped area" I didn't say it was in a revamped area.
If say Khaz Algar was its own separate zone or continent (which is likely), it may borrow a lot of celtic/irish folklore... I mean like coming across the WoW version of Cú Chulainn, who'd probably be a dwarf but is capable of turning into a hulking monster.
That's just one idea, and while we have had references to irish/celtic folklore in some areas, we've never went fully into the idea for one specific area.
