Aventen is named for a tactician-philosopher whose treatise on leadership is known by every turian youth who pays attention in class. It is a small, hot rock planet surrounded by a haze of methane and helium. It was thoroughly mined for valuable minerals in the early days of the turian space age, and since then has had little to offer. Aventen’s token spy satellites and defense drones proved no match for even a small Reaper presence, and best reports suggest they have been eliminated.

Like nearby Aventen, Caelax was named for an ancient philosopher and author. But where Aventen wrote for the military leaders of tomorrow, Caelax focused on those who feed, clothe, heal and arm the soldier. Her enormous tome, “Service” features a lengthy chapter on laws that formed the basis for the turian concept of citizenship tiers. Caelax is lower in temperature than Aventen, and its minerals were thus exploited first.

The turian defenses on Caelax are not completely destroyed, which is unusual. It may be that remnants of the scattered turian fleet regrouped using the planet for cover, and eliminated the satellite-hunting Reaper destroyers before their mission was complete. More likely, the destroyers found a way to compromise the defenses through wireless hacking, and the unmanned drones present now obey them.

“The only thing on this planet that isn’t silver is theturians. It’s all too clear they’re made of steel.” These wereAllianceheroJon Grissom‘s impressions of the turian homeworldPalaven, seen byhumansfor the first time following theFirst Contact War. The turians’ martial attitude permeates every aspect of Palaven society, from architecture to art to politics. It’s no surprise that their homeworld was never occupied by an invading force until now.

TheReapers, aware of their enemy’s reputation, brought overwhelming force to Palaven and did not hesitate to bombard cities that resisted–and all of them resisted. The dust and smoke from pulverized cities is now a breathing hazard across much of the planet. Water and power supplies have all but vanished. Still, the fight here has cost the Reapers dearly.

ALLIANCE TRAVEL ADVISORY:  Palaven’s weak magnetic field means solar radiation levels are greater than those found on other habitable worlds. Human visitors are advised to wear enviro-suits or other radiation protection when visiting Palaven.

Palaven‘s largest moon has been shrouded in secrecy since the dawn of the turian space age. During the Krogan Rebellions, the Hierarchy classified nearly all data on Menae, and its sister moon Nanus, because they feared the krogan could use the moons as weapons by smashing them into Palaven’s surface. However, some information has leaked out. Images of turian bases where personnel walk without enviro-suits indicate advanced infrastructure–likely a network of subterranean tunnels with powerful mass effect field generators that retain heat and atmosphere over swaths of the surface.

The Reapers‘ plans for bombarding the bases were met with fierce resistance by the turian fleet and the moon’s antiaerospace defenses. With their easy victory stalled, the Reapers deployed a variety of ground units to take the bases one at a time.

The turians have the advantage on the moon, but the Reapers have the patience to slowly grind them down. With every base captured, the Reapers deny the turian fleet another place to repair or refuel.

Codex Entry

Menae is one of two moons orbiting the turian homeworld of Palaven. The Turian Hierarchy put Menae in the hands of the military soon after their spacecraft first landed on the moon, immediately halting civilian research and exploration. Menae’s geological composition and specifications have been classified ever since. These days, a few active naval bases dot the moonscape, as well as infantry installations focused on extreme survival training.

The mystery of Menae is a lasting fascination for many turian citizens. Speculation about its presumably rare and valuable resources has become a common plot point in vids, novels, and even poetry for young turians.
