Darkfire Prison is a very large prison located next to the castle in Olde Darkfire Town. This prison was founded at 6 CT, near the same time as Olde Darkfire. This prison is where Nom Th-gif is holding fightmon captive. This is one of the reasons for the Darkfire War. There are many stories of deaths here from long ago, it is also said that the worst prisoners were tortured. This is where it is thought that all the fightmon are going to be moved to.
- Although this prison is owned by Olde Darkfire, frequently Darkfire will, with permission from the king, store prisoners here as well, but King Nom no longer allows this.
