"Some evidence we’ve drawn suggest it’s about five meters in height—basically a giant. Lots of muscle. We think that some of the armor designs for the Mgalekgolo—the Hunters—within the Covenant may have imitated the older Sharquoi size and function. The Covenant used them as a template, so to speak. But if any of this evidence is true, the Sharquoi themselves are far, far more dangerous than Hunters.”
	“We’ve fought Hunters,” Jai said. The Mgalekgolo were massive and strong, yet still fast in close spaces. Despite being colonies of bizarre Lekgolo worms inside nearly impenetrable armor, they fought as if they were one body. Not easy to kill.
