Eventually, Laz learned about the southern line where Athena and her people went along with the troops they had brought with them. While they held out for a while, they eventually were pushed back to the gate after suffering major losses. Luckily, once behind the gate, the special effects of the seal's power that Tamesis had activated affected them, boosting their strength and weakening the enemies. Allowing them to keep holding on. All this happened after they smash the seal that prevented them from entering in the first place.
Even then, their losses were heavy. With just two god realm beasts showing up, Athena and her sisters were pushed back and could only hold the wall after they sustained grave injuries.
But even then, they fought on.
After hearing that Laz's line continued to hold outside the gate and with reinforcements from the fortress, they were able to keep the wall. It helped that after the two god beasts appeared, none others seemed to show up.
