Approaching the ramp leading up reveals that it is unobstructed and you see the domed ceiling of the whole tower. Lightburn does notice more things besides that. He smells two... fishy humans? They appear to still be there somewhere on the floor you are about to enter, but Lightburn can sniff tracks of one of them right under his paws. A female, it seems. Went down the ramp and back up some time ago. You don't see either of them from where you stand. Entering?
