The humanoids call you monsters. Whether you are a giant, a harpy, a hag, a dragon, a medusa, a troll, or whatever else they hate, you have all been living in the region known to the "civilized folk" of the Five Kingdoms as The Barrens (in the modified Eberron setting for DnD). 

Then, three years ago, three very powerful hags, known collectively as Daughters of Sora Kell, started uniting the disparate tribes and tiny kingdoms, through guile, charisma, and sheer power of their armed forces. None have been able to stand against the battalions of skullcrusher ogres and war trolls that enforced the will of the Daughters, and most have actually embraced the new order and the benefits it provides. This revolution has basically gone unnoticed by the humanoids of the east, because they were engulfed in a continent-spanning civil war for the past century. The Daughters, however, plan to announce their presence.

The fortress of Stubborn was built centuries ago to stop the incursions from the Barrens, and the hags mean to conquer it and demonstrate the power of their new united nation. The fortress has an ancient defense mechanism built in, and the Daughters want to sabotage it before the main attack. This is where you come in.

You have all distinguished yourselves in some capacity during the last couple of bloody years, and when the Daughters announced their plan, you have been put forward by your chibs (or chosen by the Daughters themselves). Your motley crew will gather in the city of Great Crag, and be given a briefing on how to disable this eldritch weapon. The rest will be up to you.

The adventure is intended for those who have some experience in playing DnD, age is not restricted.

Character sheets will basically be entries from the Monster Manual and other sourcebooks (provided by the DM).

The adventure is meant to be a light-hearted power fantasy meant for players who want to try something new in the old system.
