Inside the Secret Realm.
With the construction of the entire Secret Realm complete, all the Bloodline Creatures had evacuated the place. Only Green remained.
Green was about to perform Other-Spacetime Summoning. Though it was theoretically very safe, that didn't mean accidents couldn't happen. If something highly dangerous appeared, having the Bloodline Creatures here might only cause trouble.
