I thought about a cycle of Mythos cards each representing one of the AOs bringing some attention to Arkham. Each of the following will have two effects; one generic, that often resembles the power of the associated AO, and one specific that will only come to bear if the associated AO is the AO of the game.
They of course vary wildly in impact, and with some of them, I am not happy. This especially counts for Eihort where I couldn't think of anything capturing his flavor.
As always, any opinion on these are welcome; and I'll be happy to consider alternate effects for these if you have any ideas.
