Shadow Milk Cookie, his master (and yours, for that matter) had instructed him to escort you to the throne room after you got back from your mission.

Black Sapphire didn't know why. You could walk there yourself just fine. Or at least, that's what he thought, until he saw you. Shadow Milk must have known what state you'd be in.
