You walked through one of Cradle's Graces main space stations, before stumbling upon the boarding bay, and what was inside of it? The Self-Ship "Creation Star Type Krun Macula", or simply "Krun Macula". Inside it was Pluto, who was testing out the Self-Ship, and its systems. She looks up at the catwalk connected above the bay, Krun Macula's head being forced to look up at you.

"Oh! Hello there! I didn't see you walk in. My apologies if I frightened you."
