The Helian War was the largest theatre of the Pan-Septentrion War, spanning across nearly the entirety of the Helian Ocean, from Dayashina to Vinya. After a long buildup in the Dayashinese Empire, hostilities officially began with the Dayashinese reclamation of Ryujima from Tyran in 1937, and the subsequent repatriation of the Divine Island Chain from Tyran and Sylva. Hostilities began with Tír Glas in 1943 with the Battle of Inishmore. The war ended with the usage of the second and third atomic devices on Dayashina by Tyran in 1946, and with the ritual suicide of Genki Suzuki and his faction.
