Not the easiest module to run, you will need to railroad your players into getting captured and if you have some above APL with a suite of spells at their disposal it isn't too difficult for them to escape the ambush. The combats are tough, challenging and outside of the initial ambush are fun. The descriptions of Hilsfar and the Red Plumes are well done and by the end of the adventure your party should bear a significant amount of ill will towards the antagonist factions involved.
