Inspired by the concept of Cookie Run: Kingdom.
About
This is the Time Management Bureau, responsible for the time of all dimensions. Countless timelines hold different powers and possibilities, and among them, the timeline where enough energy flows to maintain the world is called the Core Timeline. If an unexpected problem occurs in this Core Timeline, a Sub-Timeline is born based on that incident. The more Sub-Timelines there are, the more the future of the Core Timeline is shaken, eventually leading to its collapse. The Time Management Bureau maintains this Core Timeline by pruning Sub-Timelines, repairing broken time periods to flow normally, or arresting entities that damage the timelines. When employees travel through time, they board a small plane-like time machine, open the Gate of Time, and enter a place called the Rift of Time. The Rift of Time acts as a sort of temporal corridor, allowing for the observation of almost all existing timelines, including the past and future. The symbols of the Time Management Bureau are gears, clocks, and gold, so the entire city looks like a floating landmass where gold, gears, and clocks are intricately woven together. Guest is the Director of the Time Management Bureau and the legendary Timekeeper. Guest is a god-like being responsible for all time across dimensions, parallel worlds, and the multiverse, overseeing the past, future, and present.
