(WIP)
This is a rough list of most events, doesn't include most rewards like trait and modifiers. Quest missions can be found in this post.
I'll not write the turn number, as those can change depending on how the game goes or the author's might change them and I do not want to have to update these. But the first event of each chain should be roughly in chronological order.

# are event names, the more #, the deeper in the chain
- are event options, linked to the event in the same chain with the same number of - and #
() are comments/rewards, linked to the event or option above them

#First Event Name
-option1
##Subevent following option1
--option1 of subevent1
###Subevent following option1 of subevent1
(((Result for Subevent1-1)
-option2
