Only now have I recovered enough to tell the tale.
The badlands were fought over for the sake of obtaining possession of a magical flying fortress, filled with relics of immense magical power and value. All the nations of the Old World wanted to possess it, and so the campaign reached its climax at the very gates of the fortress.
Because I had controlled the largest territory in the Badlands, I got to start the game in possession of the fortress.

To win, I had to possess it at the end of the game.
The Enemies of Bretonnia were many. There were Wood Elves

Dark Elves,

Warriors of Chaos,

And the Empire (Not pictured.)
The battle raged on for hours. The Wood Elves struck hard at the Southern wall of the Bretonnian fortress. A Bretonnian dragon flew out to meet them but was struck down by the elite Asrai warriors. The Dark Elves advanced slowly, clashing with Warriors of Chaos to the North and East even as the Empire struck the Warriors of Chaos in their left flank. Bretonnian magic lashed out as best it could against the superior magical abilities of the enemy.
The Warriors of Chaos reached the walls first, and their general met Lord Guy deLyonesse in personal combat. Lord Guy was slain, falling bravely in defense of his King and Country. The Grail Knights rallied and denied the Chaos forces possession of the north tower. The Wood Elves pressed hard, the Dark Elves pressed harder, and began breaching the southern walls and towers. Murderous bolt thrower fire slew many brave knights in the southeast tower and Bretonnian lives ended in breathtaking numbers, yet the Banner of Bretonnia still flew over the fortress 4 hours into the game.
The Wood Elves and Dark Elves began attacking each other, fighting for one of the towers ad Bretonna threw its full weight of numbers against the Warriors of Chaos, desperately holding them back. Eventually, the Dark Elves gained the upper hand over their Woodland cousins and held the southeastern tower, and took their turn to strike the northern tower to consolidate their hold and end the battle victorious.
But Bretonnia wasn't finished yet. Peasant Men-at-arms flooded the tower and died in ghastly numbers as they struggled against the elite Dark Elf Black Guard to stop them from gaining the tower battlements.
Chaos. Fury. Death. It was a massive charnel house of close combat fighting.
Until at last, the battle was over. The fortress grew quiet...
And the Banner of Bretonnia flew proudly over its ramparts.

Guy deLyonesse was slain in the battle, and his son, a D&D character in our online D&D game run by Fathom has not yet heard, but already Lord Guy is hailed as the Guardian of Bretonnia and his sister, Repanse deLyonesse, holds the house of Lyonesse in trust until Guy the Younger can return home and reclaim it.
