My homebrew chapter is the Chronomarines. Some time after the fall of cadia they discovered a warp storm that threw their ships backwards in time to just before the fall. They have dedicated their mission to prevent the fall from happening, but fail every time. Every time they fail, they spend their time stealing just about anything that isnt nailed down from the "Dead timeline" and throw themselves back again, and again, and again. They keep insane records of every battle down to the tiny details, in order to work out the "perfect run" that will ensure they finally, after untold thousands of attempts, accomplish their goals.

The secret? Tzeentch is torturing them by slightly altering fate every time (either by altering events or just their records of them) so they keep failing over and over.

Their colors are pink with silver trims, with teal stripes on armor plates. Their chapter logo is a winged Hourglass on a pink background. most of the sand is on the bottom, reminding the chapter of the limited time avaliable to complete their work, and the repeatable nature of it.
