In our game, we have entered an area that (not confirmed) has been affected by the warp. The main discrepancy is there are 3 different things, happening in different time frames; at the same time.
Event 1: There is an epic battle going on outside the entrance to the ship. Bodies decaying/decayed, but mainly Inquistorial Storm Troopers. This initial battle was to attempt to destroy the original crew on the ship. However, there is also Dark Eldar here, and (what looks like) a Space Marine, both which are out of place, but old, and decayed, like the rest of the bodies.
Event 2: Further in to the ship, a pile of decayed bodies cover another Space Marine, but the Space Marine body is still (fairly) fresh. He appears to be part of the same squad as the Space Marine outside.
Event 3: In the Chapel, presumably the place least affected by the warp, lay the remainder of the Squad the other Space Marines belong to, along with hordes of Dark Eldar, all of which are fairly fresh. No Storm Troopers to be seen.
So my question is: Can the Warp affect the time-flow to cause 3 completely separate events to happen all at once, and several hundred years apart?
