Mainstream Bretonnian society sees Ranald as the God of Unchivalrous Victory. With the Lady having a local monopoly on protection, that leaves Ranald as the God of luck, trickery, and sneakiness, all of which are unworthy ways to achieve an objective. Some writers deign to consider that He might be needed in other lands where the local peasantry don't have the Lady and Her chivalrous knights to protect the weak, but it's generally seen that He has no place in Bretonnia as long as the Knights of the Lady fulfil their duties.
That said, there is a curious complete lack of anyone formally connecting the dots with the Herrimaults, a gang of Robin Hood knockoffs who are incredibly thematically Ranaldian.
