"Reverse teleportation?"
Inside the Undead Hall, she could control the planet, but she could not sense specific images. Still, any changes in space or energy were especially obvious to her. When she sensed someone spending a huge amount of life energy to reverse-teleport over, even Maya was startled.
In the universe, a Summoning Channel was a cheap way to travel through space. But reverse teleportation was completely different. The more powerful the creature, the greater the price it had to pay.
