Reign resumed his journey, his Undead Eyes peering through the darkness and guiding him through it . 

Well, not like he needed to see anyway, considering that it was just a straight line.

Regardless, the tunnel still looked endless, stretching into the abyss with no end in sight.

He moved really fast, but not at his maximum speed, saving some of his energy for potential threats and the long path ahead.

With his pacing, he saw a corner in the distance within 30 minutes.
