Hollow Bastion

Lore & Background

In Kingdom Hearts Re:coded, Hollow Bastion is a virtual world reconstructed from the data of Jiminy's journal entries, but it appears later in the game's progression rather than as the early visit from the first Kingdom Hearts. Within the datascape, this world becomes a battleground where Data-Sora fights against software bugs and digitized Heartless that have corrupted the journal's data. The level culminates in a major story event atop Hollow Bastion, where Pete infects Riku's code with bugs and forces him to fight Data-Sora, endangering the entire datascape.

Data-Sora chooses to debug Riku from inside, which causes everything in the datascape to reset, including his own memories. The debugging process also activates the bug responsible for the data's corruption, which takes the form of Data-Roxas—a bugged version of Roxas, not Sora's Heartless—whom Data-Sora fights before the reset erases everything.

Reader's Guide

Hollow Bastion serves as the final major level in Kingdom Hearts Re:coded before the game's climax. Players must navigate the virtual fortress, battling Heartless and solving puzzles involving the red-and-black blocks that represent software bugs. The level features the same three-dimensional backgrounds and two-dimensional character style seen throughout the game. The key story event at Hollow Bastion involves the confrontation with the infected Riku and the subsequent debugging process. After the reset, Mickey guides the reset Data-Sora to an extra world based on Castle Oblivion, where he is tested by a virtual Roxas. The events at Hollow Bastion ultimately lead to the discovery that the real Naminé left the message about people tied to Sora's heart—herself, Roxas, Axel, Xion, Terra, Aqua, and Ventus—and that it is the real Sora's duty to save them.
