While the Kavinika gave the defenders trouble, a larger and more dangerous force stalked into the cities. The Frostelus, the large, hulking creatures situated somewhere between Matoran and Rahi on the intelligence scale and somewhere between Skakdi and Steltian in height, they were large, strong, and knew that right here was a powerful source of warmth - and it was warmth that they wanted. Concealed by the same snow-white furs that concealed the Kavinika, they carefully made their way into the cities, creeping in slowly and quietly like a glacier flows across a continent.
in Ta-Karda, it was the advance group that made it in first - the smaller, younger warriors, coming in behind their Kavinika packs they had sent in. In Ko-Metru, an elder of his tribe - his armour scratched and pitted, creaking with age as he moved and seemingly supported by a pair of large Kavinika - directed the attack, sending his warriors and those of other tribes in to assail the walls of the city, to try and break them down in weak areas, climb over them where it was safe, and remove the Matoran and Toa and such from the area.
When Kova turned to find Inicara still following him, and he frowned. "You know, Ini, it really isn't that safe he--" he stopped speaking, turning to see a quite large beast jumping out from an alley, four clawed arms waving menacingly in the air as it glared at him. "Yes, it definitely isn't safe here," he said, pulling out his sword. "We should probably run now."
In Ta-Karda, the besieged Methroda soon found herself aided by tongues of fire licking at the Kavinika near her, the flash of a steel blade biting into one of the Rahi's bodies letting her know - for sure - that help had arrived, in the form of the Toa she'd recruited to help her earlier. Reaching over and scooping Methroda - and her weapons - up in one arm, Maira quickly ran out from the area, shooting flames back at a few of the wolves to keep them away before running down a clear alley.
"You know," Maira growled, "You really should've gotten some help with you from wherever it was that you were last."
And in another part of Ta-Karda, where the largest group was that was defending the town from Kavinika, the Frostelus who had first called the attack stepped into the fray. As Zinyn prepared to fight the Kavinika he had just tackled, a clawed hand reached out - almost out of nowhere, though as the furs worn by the Frostelus rustled and moved its shape became more visible against the snow-covered streets and buildings - and grabbed him by the shoulder, picking him up and tossing him back to the rest of the group he'd been with without any seeming effort, while another was brought down to grab the Kavinika that had so nearly begun fighting with the Toa of Ice he'd just thrown off.
The Frostelus quickly raised its head, letting out a shrill cry that would be heard by other Frostelus nearby - those that would first repeat the call to the larger group lying out on the frozen plains, telling them for sure to come to the city, and those who would then come to his aid for this battle.
