The Immortal

For many decades has the Tas been terrorizing this kingdom. Its appearance changes every time it is seen and some even say that it has been reborn once, as it appeared much bigger and more savage than before. The Tas is a dragon with two heads, one that breathes fire and another which blasts lightning. It is the size of a castle wall and has claws that seem to have the same powers as its heads. It is said that its right claw can turn steel red, while its fire breath can melt it on the spot. The left claw has the power of a lightning bolt and can paralyze you just from a touch while its breath has the power of an entire lightning storm. The lightning itself can paralyze you and melt any kind of metal. By being hit with it you risk having your armor melt with your skin. The Tas always follows the lightning blast with a thunderous roar, and if the lightning did not paralyze you, the roar will force you onto your knees. When it expands its wings it must be at least 50 meters wide and with a flap of them it can blow away even a siege cannon. Upon the dragon's body you can see scars from past battles, scars that many of the most seasoned of warriors can tell you how they placed it onto this horrible creature. Its scales are like plates of violet rocks and its flesh has never been seen by those who survive.
I have fought it only once before and managed to escape it with half of my armor shattered and my right arm was numb from the elbow down. I could barely carry my sword as I managed to run out of the cave. It burned my back and to this day I have the scar of that last final blast. Very soon I will fight it once more, for the last time.
