After fending off an attack on Kingdom Foxes, Luna wiped every guild but Avicia; Avicia joined on 17 Jul 2019 and Luna held the entire map — a control that lasted until Terra took it on 8 Sep 2019.
In July 2019 Luna reached its peak. Kingdom Foxes had joined on 8 Jul, ending five months of war[1]; Luna then fended off an attack on its newest member and wiped every remaining guild from the map except Avicia. On 17 Jul 2019 Avicia joined the alliance, and Luna held the entire map[1][2].
It was the third full-map hold in the recorded era, after the Coalition's dominance from Christmas 2017 and The Federation's eight months and twenty-five days across 2018[3]. Luna's proved the briefest: Emorians and Avicia revolted on 29 Aug after a leadership dispute, Terra formed in the chaos on 30 Aug, and on 8 Sep 2019 — after The Simple Ones defected — Terra took the map (Luna-Terra war)[4]. Luna had held it for 53 days.
At its height the alliance counted roughly ten guilds, including Imperial, Emorians, Blacklisted, BuildCraftia, The Simple Ones, Kingdom Foxes, Caeruleum Order and Avicia[1].
