We ran a postmortem at the conclusion of our first scenario, in which a corrupt Masonic cabal was summoning an Outsider, and one of the players commented that for a first scenario, the stakes were pretty high - higher than they were expecting. Not that they weren't up for it - it just seemed that a much greater Bad was going to happen than, for example, "Storm Front" and, in fact, many of the subsequent cases. At least, that was the impression the players got.
