Time Cube

History

Jihan uses the Time Cube to imprison Jaehwan and Ethan Cart, noting that the same Part helped subdue Andersen five hundred years earlier. It is reputedly strong enough to seal a being on the level of the Metaverse's Six Gods, but the captives damage it from within and their allies recover the cracked Cube. (Chapters 123–126)

Jaehwan repurposes the prison on the seventh floor. With technology supplied by Ethan and experience building a Tower of Nightmares, he seals damage in the Part and turns its accelerated interior into a training ground. Teams of gods spend ten internal years learning Stab while only ten minutes pass outside, then emerge to free other Anonymous Gods. The repeated cycles leave the Cube close to breaking. (Chapters 141–142)

Arteina eventually withdraws into Yesterday, leaving a Time Cube behind with her dream still running inside until her World Power is exhausted. Jaehwan keeps it at Runald's request. The Leader later reveals a larger and sturdier cube that imprisons Yu Seolha, but the text distinguishes that object from the damaged Time Cube used on Jaehwan and Ethan. (Chapters 147–159)

Properties and use

The Time Cube is a Part that seals gods inside an accelerated time prison. Its ratio is adjustable or at least variable: during Jaehwan's training program, ten external minutes equal ten internal years. The separation lets prisoners experience long periods while almost no battlefield time passes outside. (Chapters 141–142)

The Part is not indestructible. Attacks from within crack its surface, and extending its use requires Jaehwan to patch holes temporarily. Intensive training cycles nearly exhaust its durability. The corpus does not establish whether Arteina's residual cube is the same physical object after a transformation, so its identity is treated conservatively. (Chapters 126, 142, 147–148)
