A murk wraith doesn't pursue — it stands in whatever shadow is available, waits for eye contact, and asks one question. Nigel Hapworth the librarian had one ask him what he knew about dark matter at the hinge on Middlewood Road; he didn't answer, went to work, and was annihilated at The Hinge by Besd'y. His query on the hivemind is still pending.

Fishing in The Dark Peak is called slipping — the fish are slippers, the act is slipping, the person is a slipperman — and the sign on the Loxley that reads "No Slipping Past This Point" is not about the bank. Species include snarljaw, rainbowslid, dullslid and fallclimber. Why slipping is prohibited at that particular point is not explained anywhere I can find; presumably the District Council has its reasons.
