(Source: Guinevere and Lancelot, by Arthur Machen)
Our lovely queen doing secret magic devil deals, with a stick and some help from one of Camelot's sorcerers. This is probably worse than the time she restarted a war for the same Lancelot-centric reasons.
What's interesting is that it's implied Gwen makes sure noone can notice via magic and that Lancelot does try and fight the spell:
I just remembered Arthur Machen's "Guinevere and Lancelot" just now.
And in the year of our lord two thousand and twenty-six, it's now even more grimly amusing.
For many an hour I strayed through the maze of the forest, turning now to right and now to left, pacing slowly down long alleys of undergrowth, shadowy and chill, even under the mid-day sun, and halting beneath great oaks; lying on the short turf of a clearing where the faint sweet scent of wild roses came to me on the wind and mixed with the heavy perfume of the elder whose mingled odour is like the odour of the room of the dead, a vapour of incense and corruption.
Arthur Machen, The Great God Pan
This has to be the most Trench Crusade-idea that I have ever stumbled across.
