The patterner is waiting...

In the warm waters of the southern ocean, among the huge corals and the remains of ships, there lives a pattern — a large creature with a dome and tentacles, covered with luminous patterns, as if drawn by an unknown artist.
 
These patterns are not static: they shimmer and change, forming bizarre signs and symbols. The madman, who saw the sword of Scaurus in the depths, said that the Pattern is the eyes and ears of the Nameless, left to watch the Sphere. Thanks to them, he knows exactly who to leave behind during his return.
 
The Ericurian magicians who studied the patterns noted that this is just a deep-sea creature that is deadly to humans. Its tentacles contain a poison that instantly paralyzes the unfortunate. And the patterns do not shimmer, but only create an illusion due to the refraction of light in the water.
