Vast migrating herds of woolly bison, tundra horses, bighorn sheep, Irish elks, woolly rhinos, mountain goats, taiga giraffes, boreal camels, Elasmotheriums, mountain reindeer, woolly elks, musk oxen, woolly mammoths, highland oxen and northern mammoths were marching through the icy and treacherous slopes of the Glacier Mountains, ignoring the icy winds and deep snow as they continued marching through with determination. However, the herds don't know that they're walking to a certain death trap.

A mated pair of polar variants of Tyrant Wings were watching the herds as they get closer to their side of the mountains, it's been few weeks since these dragons had been last fed and this time, they're very hungry and ready to hunt for their next meal. One of the woolly bison, a large bull sensed something was wrong and it looked up and sees the dragons, it bellowed in panic as the herds stopped and see their attackers.

The male Tyrant Wing leaped down with a loud roar, spooking the herds as they began to stampede in panic. Then it sees a woolly bison fleeing in terror as it was separated from the stampeding herds as the Tyrant Wing made a dark smirk, he likes it when his prey runs for their lives. The Tyrant Wing eventually gives chase after the fleeing herbivore ruthlessly, then burst through the icy walls.

It was the female, she grabbed the woolly bison by the neck with her jaws and slammed the large herbivore to the ground with force. The woolly bison bellowed as the male Tyrant Wing tackles it down to the ground, landing the killing bite to the neck, killing the unfortunate animal.

After killing the bison, the Tyrant Wings nuzzled each other and the two dragons raised their heads and let out loud thundering roars as the roars echoed throughout the entire mountains and they began to feast on their next meal, coming out of their cave is their three hatchlings, they went to their parents and the family began to feast.
