Excerpted from A Pack of Secrets, one of my Metamor Keep stories:

"Is everyone all right?" Merideth called out. Into the replied affirmations (and one indignant "He bit my ass!"), Swift Shadow interjected a short, sharp bark of alarm. The young she-wolf stood high on the bundle of tree roots that Cloud Walker had just departed, her eyes and ears fixed intently on the mountain at the head of the gorge. A moment later, as silence fell on the group, everyone else heard it, too: a high, groaning strain as the entire mountainside creaked and shivered.

"Get out of there! Get to high ground, now!" someone shouted. It might have been Laura; it might have been Allart. It might even have been both at once, a warning to the trailblazers still in disarray down in the gorge. Whatever the case, the shout was almost completely buried by a tremendous cracking bang. A deep crevasse opened in the snowfield on the mountainside high above, and a massive slab of snow began to slide downward. At first it seemed to move deceptively slowly, but it rapidly built speed with a roar like rolling thunder.

That roar was met with a rising scream as Xavier, realizing that the avalanche would be on top of them before the trailbreakers could get to safety, met it with all the power at his disposal. The gust he called built from a tree-swaying breeze to a snapping wind to a howling gale and beyond, racing up the gorge to meet the oncoming wave of snow and blast it to powder. It wasn't enough. The leading edge of the slide blew away like a cloud, only to reveal large tumbling blocks of snow too massive to be balked even by the desperate hurricane Xavier was throwing at them. Forked lightning detonated the leading blocks with ear-shattering peals of thunder, but they were quickly replaced by the slide's seemingly inexhaustible supply. Indeed, the wind and the thunder were worsening the slide, shaking even more snow from the mountainside and sending it cascading inexorably downward.

Art by the astonishing  darknatasha. I'd never pictured Xavier in a cape before... but I will from now on!

If you want to read more, A Pack of Secrets can be found, along with many (many, many, many) other stories at the Metamor Keep Story Archive: http://www.metamorkeep.com/stories/ It is one of, if not the longest continuously-running shared story setting on the 'net, certainly the longest within the furry fandom. If you decide to read the archives, pack a lunch. Bring a suitcase. Book a weekend. It's absolutely worth it, though, for fans of high medieval fantasy.
