Clearing a Path

A moment later, Cassie and Nephis landed behind him. The water splashed quietly as it licked the shore of the drowned island, the black vines glistening with crimson luster in the blaze of dusk. Apart from that gentle sound and the whispers of the wind, the dark garden was silent. 

Sunny lingered for a few moments, extending his shadow sense outward. Eventually, he shook his head and said warily:

"There's movement."

Which meant that there was none.

The dark vines also did not seem to exude poisonous mist, and neither were their black flowers full of parasitic pollen. As far as Sunny could tell, the garden of thorns was entirely safe.

They were not taking any chances, though.
