Korius' thoughts were interrupted by Talin's little question, "Yes, and much more. When someone without enough power recites the incantation, they initially do become a dragon. However, the side-effects are most harsh. If you don't have enough power and magic to support the spell, all the portions of the dragon then recede into your body. When that happens, your body over exceeds its carrying capacity and explodes. That's why it's deadly. Becoming a full-fledged dragon or dragon-Kin inexorably increases your overall body size, and additional appendages and body parts like horns, scales, extra large tail, oil glands in your mouth. When you revert, it takes all that you gained and stores it in your body. Dragon bones and your original bones in the same body, more than enough to kill anyone. However, your transformation only gave you horns and a couple scales. They'll lay dormant in your body until they decompose in about 20 years or so. That's about the average shedding cycle for most dragons."
