Tense silence

As Nero pulled out the card Echo Location, he found it ironic that he was using the cards given to him by the army to hide from them. Nero and Gabriel quickly made their way through the facility, even using Muted self to ensure that they made no sound. 

Their journey to Carin was smooth, though the journey back promised to be tougher since his corpse was far from light. In fact, Nero almost immediately began manipulating his internal aether so that their return would not be slowed down.

But the more rush that they were in, the more careful they needed to be. Although Echo Location was good, in the sense that it would allow him to see past corners, it had a limited range, which is why Nero kept his ears strained the entire time.
