He wasn't supposed to be here, at the Inner part of the island, where strong beast fighting for survival and defending territories.
Along the way, Ned encountered beasts in a group not less than a couple of dozen. They seemed to be marching in one direction—to the base of the mountain.
Supposedly, mountains going active were left out. But it seemed that it was quite the opposite. Instead, beasts were marching toward the mountain.
It would be impossible for S'vokalt to gather them since the last thing Ned knew was that she was flooded with lava along with thousands of her minions. But it was also possible that the chained Mother was alive.
