The Ark

"Welcome to the Ark. Well, the outside of it. No... I didn't name it." 
-Arcturian
Arcturian's Cluster, more commonly known as The Ark, is a sector of the Shattered Halls that contains all the universes that have been put under the administration of Arcturian Aru. According to Proxima, even though it contains over a centillion inhabitants, it is one of the smallest regions administered by the Star Kings. 
Arcturian's rule over the cluster is practically non-existent. While many, like Centauri and Proxima prefer to directly control their worlds with their omnipotent power, Arcturian prefers a highly laissez-faire approach, and having these worlds have their own stories.
