What would be the Navy's response to finding a civilian warp ship which had been allegedly attacked by Eldar pirates (Dark Eldar, but I don't think most Imperial organizations really make much distinction between the two) where all but one or two crewmen (who tell the tail and thus alert the Navy that it was Eldar that had done the deed) were slaughtered or missing?
If the Navy personnel take a closer look and find the shrines aboard the ship desecrated in a most appalling manner with evidence of them being used as torture and slaughter chambers and twisting runes that makes the mind hurt carved into the defaced saints that once watched over the temples, would their response change from what it previously was? If so, what would their new response be?
Would they keep the men who survived alive or would they execute them?
No matter the Navy's response, would the Inquisition be alerted and, if so, how would the Navy go about doing such?
Thanks for any answers to this bit of gray area I have suddenly found my self stumbling into with my groups most recent case.
