1000 features, traps, and other things to spice up a dragon's lair

[Ketherian]

72) The maze is filled with numerous branching corridors, each of which dead-ends. At the base of each wall is a small mouse-hole that clearly leads into small rooms. These rooms lead into further branching corridors that, again, dead-end with mouse-hold containing walls. The dragon keeps a lot of cats. They are trained not to eat the mouse who can breath fire (or whatever); but are voracious for everything else. Cross-breezes abound in these rooms, as does the stench of ammonia (litter-box smell).

 

[Electric Wizard]

73) The dragon is the guardian of a vast library. Most of its books are mundane, but they are deemed dangerous by powers that be or simply very rare. The dragon is loathe to destroy any of the precious books, so clever adventurers can use the bookselves as cover.

 

[Razjah]

74) Genealogies dating back hundreds of years. The dragon has been pulling strings and making subtle moves to influence how the mortal races have been breeding. The dragon is trying to find the perfect mix of traits before mating with a mortal to create a draconic Kwisatz Haderach. (Yay Dune!)
