This scenario allows for various PC outcomes/actions but becomes quite confusing due to layout and vague writing.
A flow chart would actually have been VERY useful here.
Word choice added to the confusion. Example (modified to avoid spoilers):
"The creatures that assailed...left a clear trail back to the fields.
Here's the problem: depending on PC choices, the creatures didn't necessarily go back to the fields! In a scenario that's already very confusing this example of iffy writing needs to be avoided in the future.
