Obsidia Expansion introduces powerful new factions, technologies, and mysteries born from the world of Obsidia.
The core of the mod is the Obsidia Empire - an ultratech military society at the peak of its research, seeking galactic expansion while rejecting all others until their trust is earned.
The Empire’s forces are divided into four main corpus:
- OMC - Obsidia Military Corpus - Use weak but rapid-fire weapons. Equipped with standard medium power armor.
- OTC - Obsidia Tech Corpus - Use energy weapons of acid, cryo, EMP and fire elements. Equipped in light power armor with strong resistance to harmful effects.
- OCC - Obsidia Crusaders Corpus - Use slow weapons with explosive ammunition. Equipped in heavily protected heavy power armor.
- OEC - Obsidia Exalted Corpus - Use universal armor-piercing ranged weapons equipped with blades for melee. Equipped in light power armor designed for psi casters.
From those who broke away, the Obsidia Drifter Clans emerged, divided into three paths:
- Obsidia Syndicate Clan - sudden and violent change, thriving on raids and plunder.
- Obsidia Renegade Clan - sworn protectors of the remaining free colonies.
- Obsidia Pilgrim Clan - ruthless traders, heartless as the void, driven by profit.
In the shadows lurk ancient and dangerous enemies:
- Crimson Arachna Cult - arachnid zealots rising again to worship their deities and exterminate unbelievers.
- Obsidia Mercenary Gangs - once the Empire’s elite, now selling their strength across the galaxy.
- Obsidia Empire Sins (Eidolons) - forsaken champions, rejected and abandoned, turning their hatred inward.
