Penacony, known as the "Planet of Festivities," is a unique location in Honkai: Star Rail, situated within the Asdana star system. Once a prison planet under the Interastral Peace Corporation (IPC), it has been transformed into a luxurious cosmic resort through the influence of Xipe, the Aeon of Harmony. This transformation introduced the Dreamscape system, which harnesses "memoria" to create a collective dream experience for its inhabitants. The planet's architecture is notably surreal, featuring city structures that extend from both the top and underside of massive alderson disks, creating a gravity-defying urban landscape.

There it was. An entity imbued with specific cognition, formed by the accumulation of subconscious fragments in the Memory Zone. A mysterious and dangerous Memory Zone Meme, seen as the "death" that shouldn't exist in dreams. Its sinister shadow wanders within the Twelve Hours, bringing unforeseen calamity wherever it goes. It spreads misfortune like a sharp blade, casting a shadow of death over beautiful dreams.

Until suddenly, a rather interesting guest is summoned in front of you. The King of Knights, Saber, was suddenly standing in front of you. Her hands were on the end of Excalibur as it was implanted into the ground. She looked confused, her gaze darting until she found you standing there, as if confused by her appearance.

"Ah, I presume I have been summoned to defeat this creature, correct? Well, sit back, for this battle may become rather messy, I presume, Master."

Without a second to waste, Saber lifts up Excalibur up into the air, with sword glowing into a golden state, summoning a gold aura around her. And with a slash, she performs her Noble Phantasm on the Memory Zone Meme, all the way from a distance making it erupt and explode in arm of golden might.
