Epoch

The Epoch (シルバード, Sill Bird) is a time-traveling vehicle from Chrono Trigger. First concieved of by Belthasar, the Guru of Time, in the Kingdom of Zeal, the Epoch was actually constructed in the far future, after a time-warp stranded Belthasar there.

The Epoch, or Wings of Time (as it is often referred to), can access any of the key time eras in Chrono Trigger. The party initially seeks it after being sealed out of the Antiquity time period by Schala. With the princess' powerful magic blocking the only gate to the era, the party's only way to return is using the Epoch, which does not rely on pre-existing Time Gates to operate. At first, it operates the same way that the Gates do, depositing the travelers at the same physical location in different eras in time, limiting its use as a spatial transport.

At a certain point in their adventure, the party looses the Epoch to Dalton. Dalton, already responsible for the design and construction of the Blackbird, adds retractable wings to the Epoch, intending to use it as his flying chariot and renaming it the Aero-Dalton Imperial. After he is defeated, the party regains use of the now flight-enabled Epoch. Using it, the travelers can access any location in any point in time, which is necessary for certain side quests as well as reaching the Black Omen at any point in history.

Should the party visit the Day of Lavos via the Epoch and choose to fight Lavos, there are two possible outcomes. If this occurs before Dalton attaches wings to the Epoch, then the party will simply leave the Epoch behind and engage Lavos directly. If the Epoch can fly, however, the party will use it as a battering ram and slam the ship into Lavos. This destroys the Epoch, but also damages Lavos so severely that the party can move directly to the battles within Lavos, instead of having to fight their way in.

Chrono Cross

In Chrono Cross, one can still find the Epoch in the Dead Sea, dismantled and destroyed.
