So, I was re-reading the spell descriptions of the Scrying and Teleport spells, deep in thought about the prevalence of the Scry/Teleport tactic that seems to dominate high-level play, when I came across an interesting passage in the Teleport spell that I was unaware of:
"Areas of strong physical or magical energies may make teleportation more hazardous or even impossible."
Booya. Right there in the spell description, DM fiat is granted to prevent teleporting at their judgment call, even without resorting to Rule Zero. Although overuse of this limitation would strain credibility, at least I can now rest easy that if I really don't want my PC's teleporting someplace, I don't have to scramble to think up a reason that they can't.
Anyway, this passage has allowed me to breathe a little easier, and perhaps it will help some other DM who wasn't previously aware of it.
