Tlön

Tlön was a world located in the Tlönia system, a part of the Demetras sector in the Trans-Hydian portion of the Outer Rim Territories. It was the homeworld of the sentient arachnoid Tlönian species, members of which attacked starships venturing beyond the frontier of the Galactic Republic.

At some point after the 6700s BBY, the Mandalorian Crusader warrior culture turned its attention toward the Tlönians, whom, according to the text Ba'jurne Kyr'tsad Mando'ad that was attributed to the later Mandalorian Tor Vizsla, the Crusaders viewed as "unworthy and unclean." By the 6100s BBY, Tlön had been depopulated and incinerated, a fact that Vilnau Teupt noted in the keynote address "Industry, Honor, Savagery: Shaping the Mandalorian Soul" at Brentaal Academy's 412th Proceedings of Galactic Anthropology and History in 24 ABY. Eventually, the Tlönian species itself was rendered extinct.

Tlön was mentioned in the 2012 reference book The Essential Guide to Warfare by Jason Fry and Paul R. Urquhart. The 2009 reference book The Essential Atlas placed the Tlönia system, and therefore Tlön, in grid square P-7.
