Season 21 The Breaking of the Bond Part 1

"In the aftermath of Ultranacious's defeat, his realm has found an uneasy peace under the rule of three sisters. But shadows stir in forgotten places, and a ghost from their father's reign emerges with a twisted heir and a hunger for vengeance.
Syrien, the mad consort who bore Ultranacious's final child, returns with Sorvyn—a corrupted wolf that mirrors the bond between Gunner and Alpha in horrifying ways. Through whispers and manipulation, she plants seeds of doubt between the sisters, fracturing their unity just as darker forces begin to gather in the north.
As the triumvirate struggles with their father's legacy and their own conflicting visions of leadership, ancient portals crack open and forgotten cultists emerge from hiding. When the sisters' desperate call for help reaches across realms, it will draw the Pack into a web of madness, prophecy, and a enemy who knows exactly how to wound them where they're strongest.
Where family bonds become weapons, and the greatest threat comes not from armies, but from the poison of a broken mind seeking to break others in return."
