Event operations are part of various limited-time events. Based on their scale, event operations are divided into major and minor, and distinguished with a prefix after part of their title such as "GT" for Grani and the Knights' Treasure with the following exceptions:

Major

Major event operations are divided into three categories, main, extra, and secret, with each event consisting of an average of eight to ten main operations.

After the major event ends, their respective operations will be added into the Terminal at various points depending on their designation, allowing them to be replayed anytime:

However, the event operations in the Terminal are subject to the following changes:

Vignette

Vignette operations are unrelated to the event's plot and while they have upgrade materials as a regular drop, the drop rate is usually around the same as in Main Theme operations, which is why it is recommended to not put aside one's other farming plans for these materials as one would for a major event. However, Vignette operations tend to be significantly more difficult than major events' operations, somewhere around or even above the difficulty of major events' extra operations, and also have a Challenge Mode version. This means that Vignette operations should be only completed once, including their respective Challenge Modes, to claim its first clear rewards which includes the usual Originite Prime, the event's currency, and plaques.

Prior to Children of Ursus, Vignettes interspersed their operations through the Main Theme episodes instead of using their own node map in the same fashion as major events. Ever since then, however, Vignettes have been using their own node map.

While major events only lets one unlock the story interludes in sequence, following the story, Vignette interludes are unrelated to each other (with an exception to Ancient Forge ones), available from its own menu and can be unlocked and read from any order.
