Tierell, a frigid world devoid of atmosphere, is nestled in the Thesme sector of the Outer Rim Territories. Vast expanses are cloaked in an ethereal beauty of ice and frost, where glaciers sprawl across the surface, interrupted only by ice-worn craters that punctuate the landscape. The planet's chilling climate and lack of readily breathable gasses present significant challenges to life, with freezing temperatures prevailing across the airless globe. However, beneath the frozen exterior, Tierell harbours a thriving society, sustained by remarkable technological systems. These ancient marvels, rumoured to be Gree or Rakatan in origin, generate breathable air and ensure habitable conditions for its sub-surface inhabitants.
Situated at the crossroads of the Hydian Way and the Junction-Tierell Loop, Tierell occupies a pivotal position within the Gordian Reach's Loop Worlds. Travelers and traders passing through the region find respite within the planet's subterranean cities, where a bustling network of tunnels and chambers supports an intricate tapestry of life. These underground metropolises, marvels of engineering and innovation, are shielded from the harsh elements above, providing refuge for a diverse population. Humans and various alien species from the Outer Rim have sought solace in the subterranean depths, coexisting in a delicate balance.
Notably, Tierell boasts a significant population of Chiss, comprising both refugees and their descendants from the conflicts that have plagued Csilla and its worlds in recent decades. These Chiss communities, operating as miniature versions of the esteemed Chiss Ascendancy, have established their own houses and familial structures within Tierell's subterranean realms. Their presence adds a unique cultural flavour to the planet's diverse society, with Chiss traditions and customs interwoven into the fabric of everyday life. While the surface may be inhospitable, below ground, a vibrant tapestry of cultures, beliefs, and experiences thrives.
Tierell's history is intertwined with the rise and fall of galactic powers. Originally colonised during the expansion of the Hydian Way, the planet became entangled in the machinations of Darth Revan and Vitiate's Sith Empire during the Old Republic era. Their dark forces once cast their ominous shadows across Tierell's frozen landscapes, leaving echoes of ancient conflicts etched into its icy crust that remain visible to this day. During the tumultuous era of the Clone Wars, Tierell seceded from the Galactic Republic and aligned itself with the Confederacy of Independent Systems. This decision, born from grievances and political calculations, altered the course of Tierell's destiny and saw the planet become a key strategic world in the Separatist Alliance over the course of the war. In the present, Tierell remains a member world of the modern day Confederacy, affirming its allegiance to this renewed alliance. The subterranean cities continue to thrive, acting as resilient bastions of life against the planet's harsh environment. These underground havens of civilization serve as a testament to the resilience and adaptability of Tierell's inhabitants, who navigate the frozen corridors, forging connections, and preserving diverse cultures against all odds.
