Terrible Challenger

Two weeks after Sunny had returned to Antarctica, he stood on a cliff overseeing a vast scene of devastation. In front of him, a great valley was formed from collapsed mountains and stone debris, the ruinous landscape now covered in ice and snow. 

This was the place where Sky Tide, Wake of Ruin, and Dire Fang had battled the three emerged Titans — Whispering Legion, Goliath, and Winter Beast. The Whispering Legion had been slain, while the other two calamitous abominations drove the Saints away. An entire span of the mountain range had been demolished in the process. 

There were Nightmare Gates hidden under the crushed stone, without a doubt, or maybe above it. 

Sunny could not see, because most of the valley was hidden by a raging blizzard. This blizzard was the very same that had once enveloped Falcon Scott, sapping the lives of all its remaining inhabitants. 

It was the manifestation of the Winter Beast's authority.
