Rock fall, everyone dies is the most popular way to abruptly finish a role playing game session by the Dungeon Master.
It is unavoidable, unblockable and unevadable, thus it is the ultimate reason why one should not mess with the DM.
The phrase and the method has been around since the 80’s or 90’s, although it is highly speculative to try and find its origin.
Comics and several other mediums related to role playing games featured the occurrence in the 2000’s.
On November 29th, 2015, a thread appeared on r/DnD, inquiring about people’s experiences with the punishment.
The thread received 63 comments, as of February 28th, 2021.
In 2016 a book was published by Lindsay Ribar, titled “Rock Fall, Everyone Dies”.
