A potential aftermath to this event: https://www.furaffinity.net/view/56848361/
Thankfully Azar did not end up permanently trapped within the crystal cavern that caused his rapid increase in girth and width. His own weight was enough to break through solid crystal and stone and free him from his potential prison and away from the effects that had fattened him up. Of course, that still left him an immobile ball of scales and pudge. A rescue team was eventually sent to check on what had happened to the noble dragon only to find him in his helpless state. With no small amount of funding from Azar to keep them from spreading word of his predicament, the team worked together to move the dragon to a safe location where he could rest and recover, working to lose enough weight to make himself mobile again.
It took months but eventually Azar was able to get his paws to the ground again. Feeling more confident, Azar felt like taking a walk around the area. However, he wasn't quite used to getting around at his new weight, and a shortcut between two trees that should have been an easy pass ended up with him in an all-too-familiar situation. Grumbling at whoever put those trees there, it's going to be a long while before he gets used to heaving that much belly around. And with his hunger having grown along with his waistline, it's unsure if he'll ever get much slimmer.
