Might be considered a spoiler by some, but is probably an important rule clarification for others, in particular new players: Better double check Appendix III of the Rules Reference before playing this game.
Important of note is, that damage and horror from traumata are taken in step 2 (and only at that time, Voice of the Messenger for example does not dish out immediately an additional damage or horror from the trauma you take), while reading the scenario introduction is step 9. So, if you happen to take a trauma in the scenario introduction, you won't start with the additional damage or horror until the game after this one. That's different to all of the in between traumata you might gain in The Forgotten Age, because they happen in interludes, and hence after the previous game, before setting up the next one.
