🌍 Planetary Overview
Zel Secundus is a scorching, hostile world, enveloped in thick yellow haze and ruled by extreme geology and climate. It is infamous among Imperial scouts and Inquisitorial reports as “a sickly yellow eye staring balefully into the void” wh40k.lexicanum.com+11calixipedia.fandom.com+11wh40k.lexicanum.com+11.
- Surface temperatures are extreme; the planet is subject to near-continuous sandstorms, acidic rains, and corrosive winds that strip flesh and contaminate lungs calixipedia.fandom.com.
- Geologically unstable, the world is wracked by constant tremors, near-daily volcanic eruptions, smoking vents, and toxic fumaroles calixipedia.fandom.com+1wh40k.lexicanum.com+1.
- Toxic sulphuric pools and superheated acidic lakes dot the surface—rich in dissolved heavy metals and chemicals calixipedia.fandom.com+1wh40k.lexicanum.com+1.
🏗️ Imperial Exploitation & Survival
- Despite the hellish environment, the world harbors mineral wealth—sulphur compounds and silicates are extracted via colossal, armored crust-scrapers used in hazardous mining operations calixipedia.fandom.com+1wh40k.lexicanum.com+1.
- Only the polar regions offer any semblance of survivability, where stubborn mining camps cling to life. Their infrastructure must withstand sulphuric corrosion, protect against airborne toxins, and cope with constant dust infiltrations .
🐛 Xenos Life – Osedex
- Zel Secundus is home to the terrifying Osedex—blind, centipede-like predators that thrive in storms, detecting prey via sensitive bristles scribd.com+12calixipedia.fandom.com+122d4chan.org+12.
- They can grow to gargantuan sizes—reports suggest lengths of 30 m, with legends claiming up to 100 m .
- The creatures are aggressive and carnivorous; their armored scutes are prized by off-worlders seeking exotic protective materials—though most trade in naturally deceased specimens due to excessive risk wh40k.lexicanum.com.
