"Whoa, far out."
"You see? It's a Time Gate."
"Whaddya mean, 'Time Gate'?"

A (Time Gate, 時間ゲート^?, lit. "Jikan Gēto"), more commonly called a gate, is a gameplay and story element from Final Fantasy XIII-2. The Time Gates are connected via the Historia Crux and by stepping into a Time Gate, one can travel through time to a specific location. In order to activate a Time Gate, one must possess the necessary artefact. Some require a specific artefact, while others can only be activated using a Wild Artefact, which is consumed when used.

Profile

Only those for whom a Time Gate is intended may pass through it, otherwise, they will be blocked upon approach. It is said that only those with an affinity for chaos may make use of the Time Gates. When a Time Gate is activated, writing in Etro Script appears circling around the gate.

Multiple Time Gates can appear in each location, but each leads to a different world. This can allow access to the same world in several different time periods, and each one contains many different features: flora, fauna, and most importantly, storyline elements. Returning to places at different times is the key to unlocking the story, as some information and items can only be attained in certain times.

There are two types of Time Gate: golden gates, "blessed by the goddess and shine like the sun", and blue gates. Golden gates require special artefacts to open them, each gate needing a different artefact. Blue gates, however, can only be opened by using Wild Artefacts, which can be found scattered across the timeline.

Time Gates appear as strange glowing portals, and each requires a specific 'artefact' to activate it. By passing through these gates and traveling outside the timeline, it is said one can eventually arrive in Valhalla.
