I have no idea if this would work, but as a tribute to my mate Dave, a story idea...
In 1204 Constantinople falls to the Latin armies of the Crusades. The Franks carry out a vast devastation, and in the defence one magi Metrodorus of Thebes was prominent, sending hideous dreams to wrack the conscience fo the invaders, and stir up enmity between them and the Byzantine Prince they supported. When the city fell he swore a terrible oath of revenge.
in 1206 the Tribunal declared him outcast from the Order: for two years he had wreaked terrible magical vengeance upon the mundane families of the Lords who had destroyed his city, and brought so much pain and suffering. He was marched by Order of the Quaesitores - yet as no one knew his location, he remains at large, a threat to the Order to this day.
Cut to a hilltop in Normandy, where stood a small manor, where the beautiful daughter of one of the knights involved in the Crusade lies in an enchanted sleep. The manor is almost forgotten now - the mundane inhabitants of the region woke up one morning, and somehow forgot that it had ever stood. It had been a ruin since it was burned in the fighting between the Angevins and Capetians in the days of King Richard - who would go to this haunted spot anyway?
The Crusader and his wife have not forgotten, but he lies dead in Constantinople, and his wife is sick unto death, having never remarried. The heiress to the estates, a fine prize si lost - and many now compete for the title and lands. All that is known in that one night in 1208 she mounted a horse and left - yet as if one sleep walking. In the morning news of her fathers death arrived - some say some omen of thsi catastrophe led her to flee the many suitors who would surely await her, but others fear she is ensorcelled. Whatever the cause, her mothers heart was broken by the loss of husband, son (killed in a jousting accident) and daughter, and she has refused any marriage herself. Her liege is away in Constantinople - he will intervene on his return, but bad dreams hhaunt him everytime he turns his thoughts homeward
She lives on, still in deep, enchanted sleep. A faerie indebted to Metrodorus has cursed her, with a "condition until" spell, which requires a brave lover to awaken her. The tangled briars and sentient woods guard her bower, and strange mishapen faerie beasts lurk in the woods around her prison. A familiar enough fairy story.
Yet deep within her dreams lives Meterodorus. He had her placed here, set up the magical guardians, and physically entering her dream he waits in her sleep, enjoying the soft pastures and noble city of her youthful innocence, protected by the dream knights she often dwells upon. In her sleep he has found haven, and here in her dream he has built a tower, and there within a laboratory, and rarely now does he enter the real world to fight on. Why bother, when here he can work uninterrupted, and enjoy the youth he had long forgotten through the world of her fancies?
Occasionally he enters the dreams of those she loves, and toys with them, or calls others to the manor by dream sendings. On arrival they meet a sudden death - and he takes whatever he needed from their bodies. Carters with mundane good, apprentices charged with collecting vis, scholars carrying books, their bones all lay in the oubliette of the ruined manor.
And if she wakes? Then his haven is dispelled, his work undone, and he will reappear, and seek vengeance on those who brought his curse to an end...
Dunno, just a silly idea. Anyone else?
