Lala

You enter a large Mayan tribal city, where you eventually meet with Lala, a war councillor who means to aid your war effort. She admits her task force is spread thin, dealing with invaders of her own. She suggests that the two of you take on a sizable force with traps and tricks. They wear metal suits, that arrows can not pierce easily, and they have weapons that use explosions to propel metal balls at amazing speed. We must be careful, and stay out of sight, counselor.
