So just finished playing this last week we all got through alive. The basic story framework is great although the main npc characters all jump to spurious conclusions based on no real evidence or anything resembling a thought process oh and in typical PFS fashion are entirely useless.
The actual encounters are terrible and clearly not written by someone familiar with the pathfinder rule set. All the combats start with a bunch of prescripted nonsense designed to try to kill as many players as possible before they are allowed to act.
If you have the option to avoid this module do so. Even worst than echoes of the everwar which has 6 overlapping paralysis auras ambush you in a 5ft wide corridor.
