The Dreams of Ruin
Designed to remedy the lack of "end game" content for Old School-style gaming, The Dreams of Ruin is a setting-neutral adventure supplement aimed at characters of level 12 to 16. The material can be used with groups from level 8 to max level (and beyond, if the system supports ascent to divinity for high-level character).
Capable of challenging even the most experienced players and most powerful characters, The Dreams of Ruin are an unforgettable addition to any high-level campaign.
But beware! The dreams are mighty and can overwhelm even fearsome warlords and powerful wizard-kings. One touch of them, and your campaign world will never be the same.
