nope... even look at your example above... no D&D source book would write that... they would have the monster, and let the DM write that if they want... but then the DM knows the players.Then at this point, I repeat what I said. Every single source of D&D canon has multiple creatures/ situations that WILL trigger someone. Based on that, every single source of D&D canon needs a warning label.
The basic books are pretty dry really, by modern sensibilities the violence's is cartoony (no blood unless the DM adds it, you can be hit in the face by a giant club 4 times and not even be winded) there is little to no sex and no nudity or even hint of either really at all...
