Here's a 100+ random complications that you can add to Keep on the Boarderlands. There are some really good ones like:
38. An arrogant, high ranking cleric comes to the keep and "fires" the chaplain for alleged sloppy observance of obsure rites. He then installs the evil priest (7b) as the new chaplain, having been fooled by flattery and gifts.
63: The Corporal of the Watch (Keep #3) is a spy for the Chaotic raiders in the forest (Wilderness #3). The Corporal is a good man, and is only betraying the Keep because the raiders have his daughter. He believes the girl to an abducted, innocent hostage, but in fact she is with the raiders willingly and is the Leader's lover.

Elfmaids and Octopi has 100 shonky deals in shadelport and 100 big shonky deals in shadelport.
That colony of roaches with the weird markings on it's back? It's a spell book. Seriously, check out this post on Goblin Punch. You won't be sorry. You might go insane, but you won't be sorry.
Spirit Magic for Labyrinth Lord from Brett Slocum at The Eye of Joyful Sitting Amongst Friends is a happy accident that resulted from a misunderstanding about the OSR Superstar Competition.

Speaking of, dungeons tend to be foul places full of bad air, unless of course they include some vents, like these from Fame & Fortune by satyre.
Potion side effects! from The Dragon's Flagon, because magic is weird and dangerous.
