The After Colony timeline, or AC for short, deals with the events of Mobile Suit Gundam Wing and its follow-up New Mobile Report Gundam Wing: Endless Waltz. This series is set in a universe in which the Gundams are the primary arm of the space colonies' resistance, rather than forming a small part of a larger army. The After Colony timeline ends sometime before the present-day events of Frozen Teardrop, and is continued in the Mars Century, or MC era, during which that novel takes place.
