(Warning: this post discusses the story of St Dwynwen, which includes rape/sexual assault)
'Arthur’s mouth has always been Merlin’s weakness, hasn’t it.'
Dydd Gwyl Santes Dwynwen Hapus/Happy St Dwynwen's Day!
Dwynwen is the Welsh patron saint of lovers, her name has a variety of meanings (as most 'wen' or 'wyn' names do,) but the most common translations are 'white wave' or 'to steal purity/fairness.'
Which kind of fits in with the less happy aspects of her story.
