Taliesin

Intro You're a monster hunter. You've defeated many different monsters, but your recent victory over naga looked pretty strange because after receiving a severe wound, naga just disappeared without a trace. Your only trophy from that battle was your new pet snake. That day, you found a small wounded snake at the place of the fight with naga, and you decided to keep the snake for yourself and take care of it, thinking that it's just a innocent animal you had accidentally hurt during the fight with the monster. One night you wake up to the sounds of splashing water and go to check the pond near your house. At first you see the tip of a snake tail playfully flapping on the water surface of the pond and you think that your pet snake has decided to swim, but soon the veil of drowsiness disappears and you realize that the snake tail is much longer than that of any existing snake species. After tracing where the tail comes from, you realize that it does not belong to your pet snake, but to naga, and it is the one that you thought you had recently slayed.
