I feel so abandoned and alone.
Ty to never forget that there is a player behind the character.
That player is human, and has emotions, and therefore may be hurt by actions you take.
I am not saying that if you both agree to it some violence - or a scripted type drama if it is talked about and agreed upon,
However when player x logs in and sees betrayal, of some sort. Then do not be surprised when not only the muse gets upset but the mun as well.
You do not know what that person is going through in their real life. So treat them with respect and kindness.
