Iyronisti (culture)
The Iyronisti were once among the most powerful of the many tribes which inhabited Malcois, it is the topic of much scholarly debate if the name 'Iyrossi' is derived from them or vice versa, or perhaps a mere coincidence. Their isolation in the Teron Valley led them to develop strange customs considered absurd even by Iyrossi standards, preventing women from drinking alchohol and banning certain genders from wearing specific colours.
Their peoples were almost wiped out by a series of despicable slavemasters, using them in deranged experiments designed to inflict as much human suffering as possible. Imperial authorities learnt of the atrocities and swiftly ended the practice worried that the loss in population may disrupt the Malcois economy. Those who suvrived 'The Calamity' were responsible for some of the greatest works of Iyrossi literarature, speaking of the horrors they witnessed with their own eyes. It is said that these works helped kickstart what would become the slave revolt.
