Xarax

The Xarax were a species of scorpion-like aliens. They were midnight blue in colour, had wings and were the size of cars. When injured, they would emit a smell like cloves. Their homeworld was uninhabitable for humans. (MA: Dancing the Code)

A Xarax worked on-board the Piri Reis and accidentally broke a leg during the mission to investigate the Darkheart colony. It was later erased from existence by the Darkheart. (MA: The Dark Path)

The Xarax were a species that Professor Hamilton Smith had theories on. (BNA: Dry Pilgrimage)
