Within the first few hours of Banishers: Ghosts of New Eden, you have a very important--and difficult--decision to make. As Red, you must swear an oath to the now-deceased Antea on whether you will help her ascend peacefully into the afterlife, or resurrect her when her body has been retrieved from the meetinghouse. While the game does explain that resurrecting Antea requires sacrificing as many settlers as possible with a blame ritual, it isn't clear exactly what that means. Here's a spoiler-free explanation of which oath you should pick.

Banishers Ascend oath explained

If you choose to help Antea ascend, this means that when you eventually make it back to her body in the meetinghouse, Red will allow her to move on peacefully. This is, essentially, the easier option of the two.

Banishers: Ghosts of New Eden has lots of optional side quests known as Haunting Cases. At the end of each of these, you must decide on the outcome for the people involved - usually one living settler and one ghost. For Antea to ascend, you may either "forcedly banish the ghost to oblivion" if you believe they are at fault and have done wrong, or you can ascend them with a release ritual. Either option contributes to Antea's ascent, but you cannot blame the living settler.
