Lass
Lass had been running for a while now and has already broken plenty of the grates. The sequence of using his power had made him feel a little bit tired than before "It's the first time that I used this much in just minutes." he sighed then continued on his path. Then all of a sudden, he sensed something "What is that?" he never felt it before, but something about it is familiar. He focused his senses on it, then did something new to him "... I can see a trail..." he mumbled as he got near.
Crouching, he touch the dark essence that he felt and found that it continued below "So he was in the sewers after all." then he looked inside and soon was atop another shadow, though this time, there's darkness everywhere. Only the grates lighted the underground "Well, this is an advantage for me." then he ran on the trail while making waves of darkness in front of him. He ran for a while, the trail seemed endless. But as more time passed, he suddenly felt a stronger presence.
"There's no one..." but something was amiss. He's still feeling that unknown sensation from earlier, but stronger. Lass walked towards the source of the feeling. It was vague, but it was just at a spot, the feeling that is. "... I got you!" then he leaped towards the wall. He also made dark hands that are now heading towards his target. He wasn't sure, but it seemed like there was something there.
