Ive been doing a bit of research and recently I noticed a few odd things with how the elder dragons are portrayed. Now this is all speculation so it could be totally wrong but after doing some research im gonna conclude that each elder dragon has its own assigned territory. However, say one elder dragon dies and another takes its power, that elder dragon could take the other elder dragons land. How much land an elder dragon has claimed plays into its size. I got this idea first from zhaitan. Hes about the size of 3 tequetls. Zhaitan had control or orr and that was about it. This is why i think he was so small. However, mordremoth had consumed zhaitans territory and had maguumas territory. This is why he was so large. Kralkatorich is giant though. Kralkatoriks heads alone is the size of about 3 shatterers or 1 zhaitan. He had claimed all other territorys. The deep sea dragon has about 3 times the size of terria in land since he owns the unending ocean. This in mind, how is it that he hasnt awakened. We havent seen any of his minions yet either. If hes 3 times the size of kralkatorik and never awakened i get the feeling he could possibly be dead. It may also explain why we know so little about him.
