Copy the Unren.bat file into your game folder and run it.
Choose the "Enable Console and Developer Menu" option then close out of unren.bat once it finishes (it'll just take a sec)
Launch your game.
The developer mode can do various things, but you'll be primarily interested in the options in Rowan's Chambers.
Click the "show debug" button on the bottom left, then the "events" button.
You'll be greeted with the following screen:
View attachment 1858611
Events in red have already been seen in your current game, turquoise you meet the requirement but have not been seen yet in the current game, greyish they are not currently active in the game (you'll see this mostly with the old fairy events).
For example:
View attachment 1858632
Here we have the event "francois_the_orc_chef"
In the conditions you can see that I meet 2 conditions (Week is greater than 34 and my relationship with Alexia if greater than 50) but I don't meet 2 other conditions (my corruption is not less than 31 and Alexia's corruption is also not less than 31)
You can click the "Force run now" button to see the event. However keep in mind that the even will not count as being run in your game unless you click the little "+" button next to the "Run count."
A couple caveats:
Unfortunately a lot of the event names do not use a standardized naming format, which can sometimes make finding specific scene a pain.
This will only list evens that can trigger automatically (mostly castle or map events). Some notible events that are absent are Nasim's fertility treatments, all the orc and goblin army recruitment events, and all the Rastadel events. You can however tigger the required events and/or use cheats in other areas of the debugger to give your self a bunch of gold and XP to speed up getting to those scenes naturally.
