Bitterroot Valley Today never happened before.

Winter had been only a few months old when the floods came. A short time later, his brother @Frost had vanished.

The family had never recovered from the loss of their littlest member, hunting far and wide for many weeks, but they moved on because they had to. His parents had three other living cubs to carry on raising. They leaned on each other and carried on leading their pack, seeing them through the cold season despite the weight of their grief. 

Winter found himself quietly wondering of Frost's fate as he trailed through the valley with @Arcadian at his flank.

We are close, Брат, he announced cheerfully, smiling over a peppered shoulder at his gilded sibling; he was excited to see how Whitebark recovered from the floods, and to show the lands to Redwood. I can feel it in my bones!
