Somewhere along the way, you made a huge mistake.
You got to the city. You bribed the customs agent to get in. You helped a poor, old haberdasher who was being robbed - the only decent thing to do, really - and then this monster from another dimension came out of nowhere.
It was already almost dead when you punched it and it fell over. You keep telling everyone that.
Except, now they’re calling you the Hero of Portals, the five most powerful people in the city are each clamoring for your allegiance, and just when you’re starting to think of leaving the city for good...
...a magical shroud descends around the city and traps everyone inside. Next thing you know, the place is devolving into civil war, there are monsters everywhere, and apparently, you’re the answer to everyone’s prayers.
Yeah, you definitely messed up somewhere.
