We just started the Seventh Arm, and the party really enjoyed the introduction. I use all module descriptions as suggestions so it did not playout exactly as written. I includes Odals as part of the attack on the Noble.
My party has been asking for more outdoor settings, and this one fits very nicely before going underground. I do really like the bugbear hunt and plan to have them blow a horn for two places so as to ramp up the terror factor.
