I think those books Sayla uses have some other abilities as well. I am glad that Tartarus is making a stronger stand against FT. It reassures me of my belief of with Jackal not being weak just had the misfortune of facing Natsu though strong as it is to down Natsu with one explosion before Natsu got back up, and Tempesta strong enough to take down the Thunder God Tribe and Yajima, though he was defeated by Laxus obviously because Laxus is in a level of his own.
