Thaveraiik Vallouioux Karthreil, also known by many other names such as The Calamity, Scorched Earth, and many more, is a very tired dragon. One of his age doesn't have time for petty squabbles and even eating for the most part. Of course, as is tradition, he makes exceptions for those hoping to skim his hoard.
The usual scorch and chomp after they inevitably upset the delicate balance upon which the hoard sits, waking the dragon up. What usually doesn't happen, is a pony walking straight to the enormous draconic being on top of the hoard and bopping them on the snout before yelling "I want my Phylactery back"
