Elias and friends thought it was just a storm, everyone at Avonside University did, but when the clouds cleared and the sky was revealed again, they were met with a strange sky. Gone were the city lights and everything beyond the limits of their campus, replaced by a mountain wilderness. Elias is further swept away when he is torn from his friend's grasp and transformed beyond recognition. Will the newly dubbed Ryn find her way back to her friends, and or will she return to Avonside to find it ransacked and destroyed by the strange and magical forces that inhabit the new world?

Ye Wudao, following his master's orders, crossed into the mortal world, his medical skills so advanced they could reverse fate, his divine magic alone dominating the universe. Whoever dared touch my dragon scales, regardless of their power or status, was met with instant death!
