This was exhausting. While the blood pattered evenly against his helmet, Tony closed his eyes for just a second, listening to the grind of stone on stone as the room closed in around him, spent of the energy it would take for his gut to clench in fear. They were either going to get out of here, or they were going to die just like he thought he would over a decade ago. Maybe it was a little different. That was comforting.
Still shoulders above the rot, Tony opened his eyes to fire licking at his chin then floating away in neat clusters before burning out. There wasn't much oil left. Taking a few steps back, he pressed a hand flat against where he could see the doorway, but it had no give like the first brick he moved, not even under the Iron Man's power. There was still more to do, something was missing. The room tilted like the scales, the image of them was repeated amongst the hieroglyphs, more of them slowly disappearing under the tide of blood. Wading through to meet the advancing wall, lifting his chin now to keep it above the gore, Iron Man studied the wall once more, searching for patterns or clues or even a discernible beginning or end to what should have been a story. This was just a jumble of words and phrases; scales, sun, eye, scales, underworld, underworld, sekhemti, scales, eye, djed, scales, eternity, ankh. Just one, at what would have been eye-level, dipping under a lap of blood and quickly disappearing didn't seem to repeat and made Tony's chest ache: the feather. His head turned, slower than he meant, searching the surface of the blood as though he could find the feather he had so thoughtlessly tossed aside, reaching out to press the heel of his hand to that tile in impotent frustration. It sunk into the wall easily, and, well after he had drawn his hand away and processed what had occurred, earned Tony's attention once more. The wall was still, and no rain fell on his helmet, leaving the room quiet for only the hiss of fire burning off the surface of the pool and the waves of it licking at the walls. Okay. Both hands up now, frozen in place with everything else, Tony's eyes skimmed the jumble with conviction. Eternity, scales, eye, scales, scales, ankh, nebu. He didn't need to, but he still drew in a deep breath that he held as he sank into the blood, eyes wide and only seeing black in the depth. A quick scan provided him with a perfect wireframe of the relief of the wall, chips and dents and all, but readable below the surface. There: heart. It sank into the wall as well, and instantly Iron Man felt the rush of the pool flowing out the door now open behind him, pulling like it meant to drag him through as well.
