I got involved in a war of succession, and when I came to the throne room, there was a portal to somewhere else. The DM was trying to get me to go in, but there's no way I'm wandering into a portal that goes who knows where.

Turns out, the uncle made a portal to the niece's hideout to kill her. So when he came back, I killed him and took the crown. What kind of idiot doesn't ward their hideout?
