Towards the end of the plague, Chandra noticed that it was incredibly easy to steal, loot, and get what she needed. With everyone sick, the guards rarely took steps to prevent robberies, especially in the worst-affected parts of Surna. People were too weak to stop her, and taking money from the dead was an easy task. Especially when you never had to worry about infection yourself.
This is an application for 1000 gold - the cash that Chandra looted from houses of the dead, or dead bodies in the streets. Don't really see the need to elaborate.
