The word "dungeons" is so common in D&D that it's almost comic. Yet it's important to look at what it really means and what makes a "dungeon" a unique play element in the most iconic of tabletop RPGs.
A dungeon is isolated so that it can have monsters and treasure.
A dungeon is full of discrete areas so that the encounters are distinct.
A dungeon is old so that it can have an A plot and a B plot.
The B plot has mysterious effects on the A plotThe B plot colors the dungeon. Most dungeons are re-purposed structures in remote areas being used as a base or home by criminals, cultists, or monsters. They have moved in and taken the space as their own, but the space doesn't fit them perfectly. It leaves them too spaced out to come to each other's aid if they get raided (by the PCs!) and has some lingering shadows of the past. Those lingering shadows color the treasure found there (magic items and works of art from the B-plot time), monsters themselves (some lingering monsters from the B-plot time) and secrets (passages, puzzles, traps, etc.).
The ghosts of the slain werewolves have possessed the Ogre Tyrant and his two brothers. They have started acting strange. They have ordered that the band capture and imprison villagers in the old cages beneath the temple, and they seem to be sleepy and quiescent as the full moon approaches, in three nights' time...
But there is hope... In an old situation report found in one of the first rooms, you learn that four of the paladins were lost and never accounted for. They explored deep in the temple's East wing, and disappeared. It was assumed they fell into a trap or were killed in a secret passage. If you can find their bodies and appease their restless spirits, you may be able to take their silver weapons, which are the only way you can defeat the possessed Ogre Tyrant and his brothers.
More, some of the ogres are disturbed by the Tyrant's strange behavior. Just after the PCs find the situation report, they encounter Rashga Grey-Beard, the band's elder, who will actually converse with the heroes instead of attacking them, asking them if they know any ghost stories about this temple. If they are honest with him, he will take several of the ogres out "raiding" for a while, clearing the way for them to get to the inner sanctum, where the Tyrant's brothers guard the passageway into the Killing Rooms downstairs, where the Tyrant stands silent watch over the terrified soon-to-be-victims.
