[Anguirel]

Anglo-Saxons didn't really go in for prisons, especially for ignoble horse-thieves...

A surety sounds like a vaguely good idea. Could some Mead Hall guard like, say, Garwine, encounter Cuichelm with Manawyth, hear what's gone on and take Manawyth back to the Inn under the Eorl's surety till the trial?

Another, rather desperate expedient would be for Manawyth to escape from his captors, become a wild outlawed woodsman, and then be recaptured and brought to trial whenever is convenient. It would require a rather adventurous post from me, but I think I'm up for it...
