567-908 has a scarcity of water, a relatively sparse atmosphere, and is a barren world with no registered population or government. It is a unclaimed Non-Aligned world in the District 268 Subsector of Spinward Marches Sector. This is the homeworld of the Shrieker, a Minor Race. The world was later designated Shvreeyiyi in 1201, then Denuli in 1248, then back to Shvreeyiyi. Some published charts erroneously name this world as 567-809.

Astrography & Planetology

567-908 is a member of the Spinward Main.

Skipped over in the First Survey and barely charted in the Second, Shvreeyiyi remained a backwater just outside the borders of the Imperium. The planet is divided into two major landforms, a desert continent that stretches across half the planet, and a huge mountain range surrounding a single large ocean. While technically habitable, the planet's very thin oxygen-nitrogen atmosphere and constant, unpredictable volcanism make Shvreeyiyi unappealing for colonization. Until the discovery of its native sentient species, it was considered one of the most useless pieces of real estate in the Spinward Marches. It was only later that the system name changed in the Imperial survey database.

The system contains the following planets:

• Ilgud (7.14 AU) -- Hot
• Denuli AKA Shvreeyiyi (19.55 AU) -- Thin atmosphere, 20% hydrosphere
• Uamdar (41.37 AU) -- Cold

Native Sophont: Shriekers

The Shriekers are a nomadic race ruled by a class of priests. They live in the last Shrieker city, The Great Retreat.

Their location in the system presents questions. The primary star hasn't been in its current phase long enough to evolve Native Intelligent Life; the hypothesis therefore is that the Shriekers are descended from an ancient colony. The source world is unknown; it is possible that the homeworld was in the inner system, which burnt to cinders millions of years ago when the star began expanding.

History & Background (Dossier)

567-908, known also as Denuli or Shvreeyiyi, is a poor, barren world located on the Bowman Arm in District 268 of the Spinward Marches.

• In 480, Mtume Denuli accidentally found "gemstones" (later known as Denuli Crystals) on 567-908.
• This is the homeworld of the intelligent race known as the Shriekers, and as a result the Scout Service is building a new base to study them, after their discovery by a Mora businessman named Kafka Thingvellir in 1110. The discovery of the Denuli crystals on Shvreeyiyi produced a rush to mine these gemstones. The rush was checked by the Scout Service and Naasirka.
