'You know,' he thought, 'standing stones, ancient carvings, shenanigans, an ancient rumbling ominous voice of doom that can shake the earth... If we die here, does this count as a sacrificial circle? Is my soul going to be consigned to some dark spirit's stomach for eternity or some such nonsense? Bambi mentioned a great spirit or something. Is that a thing? Is that a thing which can happen?' He pondered, a little too light-heartedly considering their circumstances. But hey, when your only other things to focus on was a giant ancient doorway of a bygone civilization playing Golum sez with a magical talking stag or the imminence of your own death by immolation, your thoughts would go weird places too.
