Sentient

	"Let me guess, something about being crafted with 'limited intelligence'? The black ka'kari was ancient when I was born., Kylar. It told you that so it wouldn't scare the shit out of you. You're sharing your head with a being who's power dwarfs yours."
	~I wouldn't say my power exactly *dwarfs* yours.~
	"Give the fucker my regards," Durzo said.
	~I loved you better than you loved yourself, Acaelus.~
	"I have to say though, if he tells you to move, do it," Durzo said.
	*Right. Thanks* The first time the ka'kari had spoken to Kylar, it had told him to duck. He didn't, and took an arrow to the chest moments later.
