Other than the Golds, Alterra had a surprising amount of external help.
For instance, there was Eloi, Bart, Bulgogi, Rolan Mercenary Team, and so on. They also came from Towns, but Twinwave was a much more powerful town, so their average levels were quite impressive at this level of war.
There was also Enok, Raz, Senson, and Puto of the Takoda Mercenary team. Although they were from a new city, their levels weren't that high yet, and many of them were within the level limit. Even if they weren't, they could contribute in other ways, like what Zaol did.
Those within the level cap fought hard and harshly, aiming to kill, regardless of who it was.
Unlike Alterrans, their hearts were not so soft.
The only exception, perhaps, was in relation to the couple of elementalists who came their way. In their case, they'd just fight until the other person was unconscious, and they'd just let them be after that. Whether they would survive in the mob was up to fate.
