This is the Last Firedrake.
He is a huge horrifying reptile! He once appeared not far from the town where Kir the Tanner lived and did a lot of mischief.
He burned down the forests, trampled down the fields, muddied the waters. And he needed so much food that he literally deserted the area. Not one brave fellow tried to defeat the Drake, but no one succeeded.
So the peace-lover Kir had to go to the Drake's cave in order to make a deal. But, unfortunately, he didn't succeed in peaceful compromising. Nobody knows what was really happening in that cave but, in fact, no one has ever seen the Firedrake since then.
