The game is so wonderful with amazing world building and characters and..unique choices. Though, i've went through every single comment and searched high and dry for a walkthrough but i cant find anything on how to get bad ending one for the LIFE of me. im genuinely going mad.
You need to be nosy both times, obsess over the fact that Heimos has the journal and a ton of magical stuff (and think it's unfair, and NOT have him in neutral or positive affection.
Essentially, any time there are three choices, always pick the top one. If you have the option to snoop, always snoop.
That should get it!
