Lind was haggard. He was not alone.
The tower had been able to resist wave after wave of wraiths but while it had stopped, he could still feel them out there.
As battle progressed, he refined his senses enough that he could actively control the artifacts to strike them before they hit the barrier. He also began to understand the concept of parent and child was not quite right.

The wavelengths of each creature revealed that to him. He had learned a lot about spiritual existence and it had improved his soul foundation far more than simple comprehension.
Still, he was locked at low Radiant Tier.
