Thank you.
The dragon is at 80N90E40Z, southbound.
Round 505: A huge, 40-foot long, reddish-brown worm with a gaping mouth enters the arena. Its body is covered in bristles. It wriggles to 75N90E and breathes out a gout of fire, which the dragon does not dodge (rolled 19 Ref save), taking 25 points of fire damage. The dragon has 143 HP remaining.
The dragon is first in round 506.
