The Evil Mages summoned horrid creatures, and using them attacked places throughout Britannia.
Although the attack consisted of small numbers, they included creatures strengthened with experimental magic. Included amongst these creatures was a Lich Lord of dreadful magical power and a red lizardman which was immune to fire.
In the end the brave adventurers triumphed and killed the creatues. However, some of the Evil Mages managed to escape from the place, and retreated promising revenge and their return with new creatures.
