The Krashoks were mix of humanoid, cybernetics and alien parts. They had ruffs around their necks. When Krashoks were promoted, they gained a new spare part. Those who were demoted, however, had a graft forcibly removed, leaving a scar to show their shame.
The Krashoks started and prolonged various wars, acting as a third party, selling their own weapons to both sides. It was rare for them to directly go to war. They were mostly led by two marshals, one to address each opposing side of a war.
They were clients of the Darksmiths in their creation of the Eternity Crystal. (PROSE: The Art of War) They planned to use the crystal to target their fallen warriors and to resurrect them, making them an invincible fighting force. (PROSE: The End of Time)
