A pair of Dungeons

I've written up 2 complete 1-level dungeons already.   The first is a pagan temple ruins, that was where Dengwur had his first adventure in Return of the Trolls.  During Dengwur's time it became a minor shrine to the sorcerer.  The second dungeon is the ruins of the monastery near Noviodunum.  The players met Abbot Demartus at this monastery several times.  He was a practical joker and had a trick stool in his office that he kept trying to get players to sit upon and fall down.   But, Demartus helped the players many times against Wulfgar.  Now, 200 years later, the monastery has burnt down, but monsters have occupied the basement.
