Yaiy'aho (0106 Ealiyasiyw B2000L6-A): Yaiy'aho is the site of an Ikhtealyo-sponsored archaeological dig. The small permanent staff is composed of a handful of scientists and robots, but transient scholars regularly arrive to assist, and the starport is almost entirely automated.
Yaiy'aho is protected by four orbiting Ikhtealyo warships; their marines are often seen at the site. The clan's interest in the archaeological proceedings is unknown, although rumors of Ancient finds and other oddities abound. -eal TD 18

Ye-Lu (1123 Core A100134-G): Navy scientists at Ye-Lu are particularly proud of their accomplishments: the Ye-Lu starport is operated by the Imperial Navy as a research project, testing the limits of robotic networking. The entire corps of robots at the facility is tied together into one gigantic master/slave network; theoritically, the entire starport is "one" robot, with only "one" brain, but the brain is dispersed throughout the complex. All communication between the robots is handled by portable meson communicators, another important experimental device developed by the Imperial Navy at Ye-Lu. -core TD 10

Year Zero: The base year of the Imperial calendar and the founding year of the Third Imperium. By selecting a base year numbered zero (instead of the generally selected year 1), the Imperial dating system became a standard number line extending forwards and backwards in time.
Years before the founding of the Imperium become simple negative numbers, and the differences between dates before and after the founding of the Imperium could be determined by subtraction. -ld IE

Yehta (0226 Dark Nebula C1008HB-A): Yehta is simply the largest of the planetoids in its orbit. Pulled from three directions by their two primaries and a gas giant, these fragments could never coalesce into a larger mass. The planetoids do contain almost every element in the periodic table, however; this area of space has been through three or four cycles of supernova explosions since the formation of the universe; each cycle forms heavier elements and scatters them. Yehta has attracted a sizable belter population from several clans (whose relations are usually rather tense). -dn TD 17

Yerlyaruiwo: This clan and its allies comprise the most powerful bloc in the Aslan Hierate. The death of the Yerlyaruiwo ambassador by the hand of Dulinor has infuriated them, along with others outside the bloc. When the Brotherhood of Tokeaias (an assassins guild) fommed to cross the Great Rift and make Dulinor pay for his great dishonor to our Aslan people, Yerlyaruiwo offered immediate and generous support.
Yerlyaruiwo philosophy pays much attention to emotional control especially in combat. The Yerlyaruiwo-Tralyeaeawi War demonstrated this talent well. While Tralyeaeawi enjoyed many advantages during that war, Yerlyaruiwo frustrated and enraged that clan to the point of recklessness, which soon cost Tralyeaeawi the war.
Yerlyaruiwo sees itself as the guardian of Tlaukhu honor. Its representatives and diplomats correct their counterparts from other major clans on points of conduct with little hesitation. They are usually the first to challenge more serious infractions. -tlau S&A

Yeyfoui' (1708 Dark Nebula A548344-B): Classified as an Amber Zone by the Traveller's Aid Society, Yeyfoui' is the site of a long, bloody clan war. The Stikeiwyasi and Ktaih clans have been struggling for control of the planet's silver mines for several years. Originally partners in the mining industry, the clans came to blows when Ktaih (the clan responsible for shipping the silver off-world) accused Stikeiwyasi (responsible for the extraction and processing of the ore) of using an outside shipper in order to cheat them out of profits. Since then, the two have been engaged in a low-intensity clan war, and little silver has been coming out of the mines. -dn S&A
