Christopher, I've replied to your post in the general
Caribbean by Night campaign thread, as it is more suitable for general discussion of the metaphysics of the campaign, recent events in it or the specifics of its villains.
I'll break my response into several posts, because, well, with the quotes and the character limits of posts, it wouldn't fit in one. First one up is about the eternal verities of the setting; I'll get back on the subjects of the PCs position as law enforcement officers (albeit Reserve Deputies) and more about Him Who Hungers in the Deep.
In this thread, I'd really like to get thoughts from forumites on the two spots I have left for scientists on the expeditions and what specializations would be most vital slash most likely to be people already close to Kessler and clamoring to go?
