The following walkthrough has been heavily inspired by; https://www.youtube.com/watch?v=uNxq2y-uPhU
Some changes have been made to the path used in the video for a clearer walkthrough. The text of the guide has been kept short and ambiguous on purpose to limit spoilers and provide a play experience where it can be referenced in game while still enjoying the story.

Every conversation option has not been listed unless it affects the story or could be misable, and assumes the reader will be talking to characters and exploring the world. Statements that seem out of context will hopefully make sense when in the right situation as you naturally progress through the game.
