Sakanians

Sakanians are presumably non-human entities of human intelligence briefly mentioned by Ngoriki in the Prologue of Pirates of the Thunder.

Origins
Sakanians, like all aliens, were not modified by Master System to fit new environments, but instead evolved out of creatures already there, similar to the original Earth-Humans with Earth.

Description
No description is given, but considering how vastly different a Makkikor is to even a band of seemingly quite different Colonials, it may be presumed that Sakanians also lack any shared characteristics with Humans and are totally different.

Pirates of the Thunder
They (along with other humans) are briefly mentioned by Ngoriki as having died in great numbers to help her escape, but to no avail.
