The Krimson Forest is located at Charred Mountain in Earthrealm. It is a location in Mortal Kombat: Armageddon's Konquest mode, but is also an unlockable arena that you can select in versus mode.
The entrance to the Red Dragon clan's stronghold lies in the Krimson Forest at Charred Mountain.
The Edenian demigod Taven battled members of the Red Dragon clan here, as well as Fujin and finally entered their cavernous headquarters.
These woods are said to be haunted by the souls of dead warriors who once fought here.
