The Ta-koro guard are fighting rahi when Jala rides in on a Gukko bird and hops off. Two guards stand by Tahu, who's just met up with them.
"Where's the rest of the Guard?" Jala asked
"Bested by the Manas." The first pipes up.
"And we will be too, if we don't get the Karzahni out of here!" A shaken guardsman says
"You wearing an infected mask, Guardsman?" Jala asks.
"No, Captain." He calms himself.
"Then listen up!" Jala exclaims. "Tahu's gonna get on this Gukko, fly across the bridge into Ta-Koro, and shoot disks at any rahi dumb enough to get inbetween him and Makuta." Jala paused. "Pull yourself together, Guardsmen, because you're going with him." The Captain gestured to the shaken guard.
"What about the Manas?" The first guard asked.
"We've all seen how the Toa beat em'. They're tough, but they aren't invincible. Stick with Tahu, he'll know what to do." Jala ordered, and the fight for Ta-Koro raged on.
