Wyvern Roost Preview: An abandoned guard post stands just off the main road, clearly having fallen into neglect. A courtyard connects to a three-storey stone tower that has begun to crumble in places, and thick moss claims most of its façade. The door has been damaged and hangs open on its hinges. The party may stumble upon this guard post coincidentally during travel, or perhaps local officials have hired them to clear it of any threats so they may conduct repairs and re-staff it with men. How will they handle the wyvern that roosts on its battlement, and what will they do with her eggs?
