Drows

Roland was now interested in finding out about those spiders.

A kind of spider that could eliminate the sound around it was probably a magical beast, and it could also build cocoons and knew how to work as a group—these spiders were countless times stronger than the giant spiders in Red Mountain Town.

What was their ability to eliminate sound, magic, or was it caused by their own special organs?

It was most likely magic, so what was the principle?

He had heard that there was a silence spell in magic, but it only eliminated the sound of one's footsteps when moving. Sounds like clothes rubbing, blood flowing, heartbeats, and so on couldn't be eliminated. These spiders, on the other hand, were clearly eliminating all sounds within a large area.

This technique was many times more powerful than the silence spell.

He really wanted to figure out what the principle of this magic was.
