<Snipped quote by Hael>

Then the Ch'ak'ii shall start building great shells to cover their worlds so that it shall always be night! I can never be invaded! It's the perfect plan!

The shells could have lights installed that flash randomly. No Xim will ever dare invade.

Well, at least, no CRUSHER. A Serpent, or a Sulkiayak might...

Like I said, there are hundreds of types of Xim- but most have weaknesses of some sort (which drives them crazy, because they are so perfectionist that a single flaw will consume their entire focus)
