The walls opened in front of him grandly as if paradise itself was welcoming his arrival. Sier could only look with awe as he walked into the fortress that began to glow with runes, coming to life. The runes masters, awakeners, and the soldiers tried to rush inside but strong wind pushed them back and the gate closed.
