Beastmen stray into Arnar Woods

The Dark Elf raids into the heart of the Domain of Beasts had a dramatic effect on the Kaalroen Empire. The lords of the towers of the Chaos Realm turned even more introspective and cut themselves off more and more from events on the outside of their borders. Their control over the beastmen of the north grew weaker, and the beastmen began to raid further and further afield.
The High Elves protected their colonies with many garisons, but the Wood Elves further south, in Arnar, were far less prepared. Their isolation from the rest of Palurin had lasted over 35 years, and now their realm had another invader from the outside. The beastmen horde blundered incautiously into the woods of Arnar in 266PC, but were equally unprepared for the reaction of the spirits of the wood.

The beastman army soon found themselves ambushed and fighting a guerilla war in unfamiliar territory. Their force was herded into a clearing deep in the forest where the kings of the woodland realm unleashed their full fury against the mutated followers of chaos. The battle soon became an utter massacre and the beastmen horde was lost to the woods of Arnar. Realising their splendid isolation could not continue, the wood elves began to expand their borders, vowing to control and protect all of the forests of Arnar.
