Tayseri Ward is the Citadel's cultural and artistic epicenter. However, Sovereign's attack in 2183 brought that status into question, and the ward's reputation remained in limbo for six years. The battle and its aftermath inflicted comparatively severe damage on Tayseri above other wards, leaving it a patchwork of reconstruction and salvaging operations.
This rebuilding effort attracted transient workers from outside the Widow Nebula, and with them came criminal organizations involved with the construction industry. A period of increased criminal activity and unrest followed, troubling Tayseri C-Sec to no end. (See, for example, the activities investigated by Spectre Mira D'Rana.) Additionally a slump in the galactic economy, coming on the heels of the Eden Prime War's cessation, impacted the struggling ward. Conditions normalized after the Systems Alliance erected their forward command center and garrison, known as the Alliance Tower, on Tayseri.
Little Rannoch: Established a few years post-Reaper War, where small but notable numbers of quarians and geth now roam the streets of the Citadel. Where Keepers allow it, colorful cloth is draped between buildings.
