-It's called godmodding.
You can't make a character, say "I'm untouchable!" and have everyone bow before you.
It's not really realistic and not fun for participating characters.
-She can't get away with it.
You can't hurt people or kill people and then have them forget one week later "because the RP is over".
-I agree with Zan, does this RP have a fixed outcome?
I once participated in a RP where someone got kidnapped. The kidnappers wanted to keep him hidden for a looong time.
But by asking around a lot in-character I found out where the guy was.
I could find him safely because they had ditched him somewhere while they were partying. So I bring him to a secure location, where it was crowded and where
there were guards.
But they then kidnapped him again because that's what their intended plan was, making themselves also guilty of godmodding.
So in-character I found the guy again and brought him to another location where we guarded him.
But when I came online after a while, of course, he was kidnapped again.
So I simply stopped coming online until they stopped bothering me.
A.K.A. RPs with fixed outcome aren't fun.
