The night air was silent.
There was a tension in the air that everything that dwelt in the forest could feel, like the calm before a storm, or the stillness before an earthquake. The promise of sudden and violent change, one not seen or heard, but nonetheless felt.
That promise was paid off when the tension finally broke.
There was a peal of thunder, like a lightning strike that never stopped, and the air split. Earth cracked and trees tumbled as the forest was forced to make room for something else, something even now was still obscured by the sight-warping haze of bent space. Animals fled, everything that could run, fly, or crawl bolting in terror from the sight, predator and prey united by fear in that one earthshattering moment.
And then, the night was silent once more, save for the fading cries of the animals as they fled.
Where once was dense pine forest was now clearing, the heavy winter snow starting to cover what was now bare red grass. Within the clearing was a tower, tall and robust, made from massive stone bricks and columns of dark purple stone, inlaid with runes of gold and light. The barred glass windows of the upper levels were cold and dark, and the only way in or out seemed to be a set of massive oak doors in the very center, twice as tall as a man.
Many miles away, those uninitiated noted their jittering instruments and told themselves of a minor earthquake. But those aware of the true nature of the world turned their gazes to the Pacific Northwest.
Something new had been placed on the board. Something strange.
A pulse came from the tower like a massive heartbeat. As it washed over the trees, the plants and leaves bent back against the unseen wind, as if drawn inexorably towards the tower. Those immense oaken doors opened with a long groan, and out came rows of figures, made from iron and thatch, who brought with them lumberjack axes and stranger things. Trees that had never known the bite of an axe begin to be felled, dragged back into the tower, down into the belly of the beast.
Something strange indeed.
