The Green Helmets (or Šebhuliam in Bulwari) were an Old Sun Sect that rose to prominence following the Decades of Devastation and their alliance with Dartaxes szal-Forramaz. As most Old Sun Cult sects, their early history is partially known from very biased sources : either Jaherian Examplars or sources from the order itself. According to the szal-Harrumanz official chronicle, the young Ashuru szal Harumanz fled North to the kingdom of Birsartanšes following the Medurabari Purge of 1220 and settled in the mountains near Kuzak and Garkas-szel-Azka where he gathered the Fardašin (Faithful).
The main difference between what would become the Green Helmets and the other sects rejecting the divinity of Elves, came from the question of lying. Truth is one of the biggest tenets of the Cult, all Sun faiths agreeing that "one should speak no lie". The sects developed a theology they called Ašanu (Bulwari for Sheltering), centered around the right to lie by omission as necessary to shelter the remaining Light. But Ashuru saw the Medurubari Purge as the logical outcome of the sects which were still easily found out because of these partial omissions. He developed a theology of Šanqu (Prudence), allowing the faithful to lie about religious affairs in the face of Elven persecution. The extreme secrecy of the Fardašin allowed them to flourish in the highlands of the Harpy Hills, Arantir of Birsartanses more concerned with the threat of Harpies than orthodoxy in the mountains. A descendant of Ashuru even rose in Birsartanšesi Human nobility, becoming the caretaker of the Kuzak stronghold, a choke point between Gelkalis and Birsartansbar. Nonetheless, these "Faithful" made themselves known by the occasional practice to send young men murder some officials throughout Bulwar wearing Green Helmets, the color of purity and faith in the region.
When Dartaxes rebelled, the szal-Harrumanz family allied with him and their fortress in Kuzak became the main stronghold of the rebellion. Eventually Dartaxes would convert to their faith, and the Green Helmets would become widespread throughout his army, as an elite and fanatical force, assembling many sects around the core Fardašin to become the mainstream theology of the Akalate of Dartaxâgerdim.
