Could it be possible that Malacath is affected by mythopoeiac forces? I know Daedra aren't, but Malacath isn't like other Daedra. He did participate in Creation, he did sacrifice himself, he was considered an ancestor, though he was Trinimac then.

We also know that the other Daedric Princes don't consider him one of them. While I realise this is often explained as befitting his nature as patron of pariahs, could it not also mean that he is still an Aedroth?

If this is the case, then wouldn't Gortwog gro-Nagorm's revival of Trinimac-worship mean that Trinimac could emerge anew as an Aspect?
