Zaralek Cavern is an enormous cave system underneath the Dragon Isles in World of Warcraft. It is accessed via a large cave between the Ohn'ahran Plains and Valdrakken. Deep beneath the Obsidian Citadel from which Neltharion once defended the Dragon Isles lies a vast hidden laboratory where the Earth-Warder conducted his experiments. The laboratory is where he created the dracthyr and ultimately succumbed to the whispers of the Old Gods². 

I hope this helps! Let me know if you have any other questions.
