Started rereading again because of the new dragon friend stuff and spotted this: you said size 2 times, it would be better to only say it once you could just remove the part in the "- -".
The trial is followed by dragon jousting. Knights are paired against each other based off -the size- of their draconic companion's size. Accolon and Sera enter the medium category, and you help adjust the former's armor while Sin checks Sera's, who's explaining to you both their strategy for the upcoming trial. Accolon mounts, strapping in his safety harness, and you hand him the jousting lance, painted a soft green that matches Sera's eyes. You send a mental cheer on to the dragon and they flash you a smile.
