"I have a feeling that, since these creatures have been dead for who knows how many years, they can wait it out longer than us. I think we should keep opening coffins, closest to an escape route first. Then kill the beasties we find. Eventually we will get to the end of the hall, where I believe the 'Master' will be. That way if we do have to lay the lead creature to his final resting place, we won't have his minions clawing at our backs."
