Deleting an Account
Coined reset in Aegis, a deleted account must start from scratch. Upon log in after a reset, the province looks like the first day you began. It is important to note that the The Delete Account button is a manual feature, but players can also reset a province by conquesting the province in question below 250 acres. An in-game mechanic forces the province to restart. Resets are reserved for political punishment after the community has exhausted measure, and is usually frowned upon. Though rare, resets do happen, and they are not the end of the world. Aegis is about building, and even the best minds have found reason to manual delete on rare occasion.
