A day later, the Kingfisher continued on its way and finally reached the boundary between the Density-1 and Density-2 World Zones.
Unlike the normal transparent barrier that separated the same Density World Zones, what appeared before the Kingfisher was a hazy barrier that occasionally emitted strong bursts of colorful lights.
It looked like a nebula, too mesmerizing to the eyes. Imagine a bunch of fireworks being shot into the sky at festivals. That's how it appeared.
Yep. It's a pretty standard name.
At a glance, the nebula-like barrier would make one cautious in approaching it.
However, it's not actually harmless. Just like the normal boundary between different World Zones, it's just a little harder to pass through them. Entering it would bring the Space Vessel or a Source Energy being into a Temporal Zone that would emulate the feeling of traveling through a portal.
