Advancing Into the Umbral Realm

As the radiant light veil faded away, Lily raised her hand curiously and saw a green leaf marking on the back of her hand. "...So this is the soul-binding mark? And we can resurrect inside the Umbral Realm now?"

"Yes, but remember, only once," Hao Ren replied sternly. Even though he had reminded them a few times already, he felt that he needed to emphasize it. "The Umbral Realm is a separate world from the Plane of Dreams, and based on Raven 12345's calculations, that place is probably within a narrow stretch between the World Barrier and the Void. As the World Tree is only in control of the internals of the universe, its powers cannot fully penetrate the Umbral Realm, therefore we have to rely on this marker to work. Without any ability to recharge, this marker has one use only."
