@NoNickNeeded Some other faction? TARTAROS! I demand Mashima show us Tartaros before the series ends. Otherwise I'll make empty threats and whine even though no one cares.

But in all seriousness, Tartaros was mentioned as some big powerful corner of the Balam Alliance, then never spoken of again. This would be the perfect time to introduce them.
