What we have so far:
-One of the original members of the Astartes Praeses along with the White Consuls and Subjugators
Homeworld:
-Necris, Death World, primarily desert. Was once verdant, but humans strip mined entire planet for precious minerals.
-Most native fauna and some flora can kill you (or at the very least ruin your day)
-Current human population are decendants of original miners. Pious and industrious.
-Exemplars recruit primarily from Necris.
-Aspirants make pilgramage across desert. First test.
-Those that survive are allowed to next stage. Tests of strength, speed, and martial prowess. Similar to ancient Olympiad with a large dash of gladitorial combat.
-Aspirants must pass every test. Those that do must complete last challenge: Kill a rock dragon (big nasty reptile, think of a cross between a Komodo Dragon and a Gila Monster on steroids) by yourself.
-Aspirants that succeed in killing rock dragon are allowed into chapter.
-Fortress-monestary "Arx Fatalis" is in northern mountains.
-Fairly standard fortress monestary.
Beliefs:
- Battle-brothers write various litanies on their armour for various reasons.
- Greater piety than most chapters stemming from constant battles against Chaos. This isn't to say that they're like the Black Templars or Imperial Word Bearers, just that they might spend a slightly greater amount of time in prayer and things like that.
Organization:
-Standard Codex organization
- More Chaplains and Librarians than usual, Each company has an integrated librarian and the Battle Companies have two chaplains.
-Captains acts more as a tactician, battle-brothers are usually led into battle by Chaplain or Librarian.
Combat Doctrine:
-Standard Codex combat doctrine
-Prefer energy weapons (like plasma guns and lascannons)
-General grudge against the Word Bearers for their corruption of the Imperial Truth and their habit of spreading heretical lies
Gene-seed:
-Ultramarines gene-seed. Probably.
Feel free to contribute any ideas you have. We'll have an Index Astartes here eventually.
