The Imprisoning War(s)
The name Hyrule gives its wars against Ganon — used for at least two different conflicts millennia apart, which is exactly the kind of thing that keeps timeline theorists up at night.
A Link to the PastDownfall TimelineThe original usage: the Downfall-era war that sealed Ganon in the Dark World, backstory to ALttP.
Ocarina of TimeShared Trunk (Before the Split)Retroactively revealed as that war — the Downfall branch's version of these events.
