Dragon skull

1asset dragon_skull "Dragon skull" complexity=9 float
2// the head of the ancient dragon the crypt was dug into: a colossal ivory skull half-buried in rubble
3// with its jaws agape, swept-back horns, a frill of spines, heavy brows over two deep sockets where a
4// red ember still glows. The goblins moved in: their banners hang from its cheeks and their candles
5// drip on its snout and chin. The lower jaw is a long U, so a throne fits between its tips in front
6// of the upper fangs. Everything sits 0.5 m low (the scene places it with lift=0.5, clear of the
7// floor checks, so the throne can stand inside the jaw).
