>>26840822They were just doing normal shit back in the day. Moving their little Expeditionary Force to its next system, everything going fine everything happy. Warp-jump. Every thing happy, sailing through the warp.
Exit warp. Count all the ships and everything is fine and accounted for.
Open auspex arrays and start broadcasting to the planet. Thats where everything starts to go odd. Check the stars. Stars are all slightly out of place. Mechanicum Adepts say their Logic Engines are telling them that the stars are in the right place if this was nearly ten fucking millennia forward in time.
Start getting messages from capital city of a planet some way into system. Already Imperial. Has been for longer than they have had written records. Ave Deus-Imperator. WTF.
Go down to the planet and start reading their books.
Go back to ships and sit in a high orbit and wait peacefully for the Inquisition to show up.
Their colour scheme was rather drab. Now they dress in white, pure as the Emperor's Divinity. Trim for librarians is blue, the colour of the scholar. Chaplains is gold trim because their words are precious and don't decay with age. Apothecaries have red trim for the life they preserve. Tech-Marines have the chrome and silver trim of untarnished metal. Captains and the Chapter Master have black trim, they remember their origins and endure the weighted chains of authority.
Scouts wear any colour that will help them blend in.
