What is onyxia of the void puzzle?

Unfortunately, as an AI language model, I do not have access to a specific puzzle called "Onyxia of the Void." However, I can tell you that Onyxia is a character in the massively popular online game World of Warcraft. She is a formidable dragon who resides in her lair in Dustwallow Marsh and is often fought as a boss in the game. The Void, on the other hand, refers to a different aspect of the Warcraft universe, represented by a dark, chaotic realm filled with twisted creatures and eldritch powers. It is often associated with the Shadow and has been a central theme in many of the game's storylines. Therefore, it is possible that the "Onyxia of the Void" puzzle is related to these elements from the World of Warcraft universe.
