History[]
Turtles of Grayskull (mini-comics)[]
Hoping to find a way to turn the tide of events back to their favor, the Ninja Turtles, Man-At-Arms and Teela travel to Castle Grayskull to find answers. A voice speaks to them as they approach and tells the story of the origins of the castle. One of the first spaces they enter is the Hallway of Holograms and Illusions. The ceiling is a vista of outer space and multiple planets, causing Donatello to comment on the "high ceiling". Man-At-Arms tells the Turtles that the Hallway of Holograms and Illusions is disorienting only if you stare into the void. Leonardo acknowledges the warning.
