Hi, this is my first post....so be gentle!
This is really a question for Paizo and while it is not really a spoiler I suppose the answer could just about be construed as one, so here goes:
I notice that in the sample characters given for Second Darkness there is no arcane spellcaster and no one with any rogue pick lock/disable trap type abilities. Does this mean that it can be reasonably expected that a party will be able to get all the way through all 6 modules without either of these abilities and it won't cause insurmountable problems for them later on or not. Having partly played through Rise of the Runelords I have been inspired to get Second Darkness to run & was wondering if it was worth prodding the players towards including an arcane and/or trap disabler among themselves or if it won't really matter if they don't.
