Reach

The title given to the individual born every thousand years, for their ability to cross the boundaries of the physical realm and that in which the Endlords reside. If the Reach doesn't die, or safely release their power, they will cause rifts between the worlds, and release the Endlords and the Unmade.

Powers

While a Reach's main purpose is to use their powers to create rifts into another realm to release Shatan Maer (Shadowflesh) and their masters, A Reach can also use the sorcery as a means to protect themselves. However, since Ash is the only Reach the reader has experience with, how this is done and what the limitations are, are unclear.

When Ash used her sorcery to save herself from rape by Marafice Eye's men, it's suspected that it wasn't strong enough to do more than perhaps create a crack. However, this could also have been the work of Baralis. It's never clarified.

Even when Ash releases her power safely in the Cavern of Black Ice, she is greatly feared by the Sull. This seems contradictory to knowledge given, that once she released her power in the cave, that she would no longer be able to release the Endlords.

Voices

Ash begins having nightmares of the Cavern of Black Ice, horrific headaches, and often hears voices calling to her. When the voices begin, she falls asleep for only moments, listening to their pleas and affections, but would wake before she "reached". When in this trance-like state, her arms will slowly lift upward, black smoke can be seen in her mouth, and the smell of metal is in the air; the latter two both being signs of sorcery in use.
