On the Bookshelves

This is an encounter that takes place in the library of a cult temple, from my latest adventure Xanadu. Even though the most useful part for readers of this blog is the random table of books found on the shelves, I've reproduced the encounter in its entirety.  

Bibliotecha

Door, sandstone, arcane locked, painted with cult symbol. Stone pillars, flanking the door, each carved with a representation of female creatures with wings, similar to statue in area 5. Bookshelves, filled with tomes, various bindings, sizes. Smells like wax, stale incense.

Door
If door is touched: it is magically trapped. Touching the door causes (d20): 

• Result of 1–18: a fireball for 2d4 damage to everyone within 10’ of the door (save vs breath for half),
• Result of 19–20: a lightning bolt to explode for 2d20 damage to everyone within 10’ of the door (save vs breath for 1d20 damage).

How to disarm the door: trap is deactivated by pressing a release button behind one of the stone pillars next to door. A thief can find this by investigating for traps. 

Bookshelves
Books of various shapes, sizes, and colors. Some are ancient, some modern. Volumes of esoterica, occult, directories, almanacs, local histories, etc. There is nothing magical here.
