You carefully go back to the door making sure to only step on the yarn tiles and open it; it opens to a small room with a dirt floor and rough stone walls, someone has scrawled "You cannot kill it with swords" on the north wall, more centipedes crawl in the dirt here, a large crack in the ceiling allows daylight to illuminate the room, a shrub no taller than 2 sword is growing here rich with tiny flat dark green lanceolate leaves.
You hear Makdt call out behind you, "Is it safe?"
You feel having conquered the tiled hallway that your experience has allowed you to reached a new plateau of readiness...
