Military: War
The displaying of certain colours was an important part of the Kelpeater Empire's caste system, and as such dyes were a significant part of their economy. While the materials to make dyes were common enough on Lorgain, there were more scarce on Waking Materia. The resulting dye prices would trigger a thriving interplanar market centred around the otherwise backwater plane, and with it large increases in piracy, and warfare between different trade guilds. Though such competition occurred before and after these dates, the period of 180-300 I.M. represents the height of the fighting.
In addition to the increase in trade and warfare, the Dye Wars also represented an explosion in sentient diversity on Materia, beyond the cultures native to the empire, marking the initial presence of species like the Qufit, Onidoshi, Halflings, Arakh and Pukwudgies, among others.
