The Valiant and the Unlucky

"Of all the legends to come from early medieval Aquitaine, whilst many were centered on the Battle of Tours - and, consequently, many poets and trobadours found a great topic in Roland and Charlemagne's knights, even until the 16th and 17th centuries - a lesser known legend, first dated to the halfway point of the 10th century, went completely under the radar.
The story of captain Sigmund and princess Merwin, possibly loosely based on true events, is rumored to have been banned by the church during the western schism and the Counter-Reformation, due to its unusually (for the time) liberal depiction of sexuality and religious tolerance.
For that reason, the last bit of historical evidence we have of it is from a translation of a Saxon 9th century retelling, written shortly before the Albigensian Crusade (1209 - 1229) and only recently rediscovered by medieval scholars hidden in a copy of Cicero's Somnium Scipionis.
This version of the story tells of Sigmund, of Faramund's house, and princess Merwin, daughter of a king Dagobert, - early medieval scholars have identified him with Dagobert I - but also of a Moorish witch, Fatima, of whom we have no historical evidence for obvious reasons. Other characters include Nescatos, on which differently dated footnotes clash over identifying him as Roland or Charlemagne himself's ancestor, and a sorcerer Attalus, who was evidently an inspiration for the wizard Atlas, a character of the Roland in Love and then of the Furious Roland.
Other odd connections with the 16th century novel are present within the legend, in which - akin to the Roland - a magic ring is given to princess Merwin, which, once put inside one's mouth, makes them invisible. The plot thread is however for obvious reasons altered in the Roland, as Merwin (unlike Angelica) doesn't use it to escape her many suitors, but embarrassing situations concerning the curse bestowed upon her by Fatima..."

The 'Valiant and the Unlucky' is a take on the medieval chansons de geste, a.k.a. early novels telling tales of brave knights, unruly giants and helpless princesses. It starts in medieval Aquitaine, but can expand throughout the early medieval world.
Yes, despite all the literature jargon, this is still erotica - the main story I'll be conducting revolves around the protagonist, Merwin, being cursed to radiate bad luck on everything she touches - including and especially clothes.

After the first few chapters, required for introduction, you may start from there in most directions (of course, I'll only consider my threads canon - no hard feelings) or just create an entirely new story if you feel like it.
The story's world, much akin to our own, does still include all the good stuff about chansons de geste: magic, giants, powerful warlocks and beautiful princesses, as well as very historically inaccurate characters.
If you want to write in verses, staying true to the source material, that's appreciated, but it's completely fine if you write prose like I'll be doing.

Big disclaimer: while I'll be referencing history, I want to make it very clear that the Valiant and the Unlucky is a complete work of fiction. None of the characters existed in real life and no scholars ever commentated upon it.

And now, without further ado...
