World of Darkness

As Sunny stood frozen in the world of darkness, Nephis summoned a Memory lantern and raised it, illuminating the deck of the Chain Breaker. A small island of warm light appeared around them — however, it was not nearly as wide as it should have been, as if the lantern was struggling to push back the unfathomable shadow. 

Its light trembled pitifully.

"Sunny… what did you do?"

He lingered with the answer, then said honestly:

"I summoned a fragment of Shadow God's domain. You must have seen it in my runes… it's a Legacy Relic I received."

The Fragment had already swallowed all of Wind Flower. Sunny could feel it… which was strange. As an Ascended Tyrant, he could control his shadows from around twenty kilometers away. However, the range of his shadow sense was much more modest, less even than that of his vision. 

How was it that he could vaguely sense the far side of the island?
