Emperor Serpentine wrote: Did you ever hear the tragedy of Darth Arcturus The Wise? I thought not. It’s not a story Wu would tell you. It’s an Serpentine legend. Darth Arcturus was a Dark Lord of the Sith (and an Anacondrai General), so powerful and so wise he could use the Force to influence the midichlorians to create life… He had such a knowledge of the dark side that he could even keep the ones he cared about from dying. The dark side of the Force is a pathway to many abilities some consider to be unnatural. He became so powerful… the only thing he was afraid of was being banished to the Cursed Realm, which eventually, of course, happened. Unfortunately, he lost a war, and was then banished to the Cursed Realm by Garmadon. Ironic. He could save others from death, but not himself from being banished to the Cursed Realm.

Later, he was released from the Cursed Realm, but went to the Departed Realm. I have a better story.
