It would be easier to guess the age of the battle if you had given a description of the state of the corpses. However, if it is recent, my guess would be that Nuva got his revenge against the Toa that locked him away.

Or, if it is ancient, it could be the remains of a battle between the three Toa, perhaps the one where Nuva and Tilira were imprisoned.

OR, it could simply be what Pirai thought, that it was a Great Being. Despite the fact that the only GB in the canon MU is Velika (to our knowledge), their could have been another one.

OOORRR, it could simply be someone from up north, perhaps a Toa who stopped by Nynrah or Xia to pick up some heavy artillery before coming down to Balfe-Nui to die.
