Nightmare Fenrir Slain[]

Fenrir’s gigantic body falls to the ground as you strike your last blow. A blazing crimson light shoots into the sky, spearing the dark clouds. Leading your army, you carefully approach this legendary creature. Its snow-white fur sparks amongst the hot blood and barren mountains. And the furious eyes, the light fades there. You know this unyielding creature is finally gone. Again, you hear the wind rustling against the rock, you feel the coldness of the sweat all over your body, and you feel the weight of your armor. Though the next challenge is already around the corner, now is definitely the time for a short break to enjoy the victory.
