How do you get the orb of the dark?

Excuse me, could you elaborate on the process of acquiring the orb of the dark? Is it a rare item that can only be found through a series of challenging quests or perhaps a reward for completing a specific task? Are there any prerequisites or requirements that need to be met before one can even attempt to obtain it? Additionally, are there any risks or dangers associated with the pursuit of this orb, and if so, what measures should be taken to ensure safety during the process? I'm quite intrigued by the orb of the dark and would appreciate any information you can provide.
