Annakarl was one of Zaros' fortresses that was located in what is now the Wilderness. It was captured by the early Third Age and destroyed somewhere between the year 3100 and 4000 during the Third Age by followers of Zamorak and Saradomin. The Demonic Ruins in level 47 wilderness are all that remains of Annakarl today, and you can teleport there with the Annakarl Teleport spell.
Annakarl can be seen in its prime during a cutscene in the Ritual of the Mahjarrat Quest. During the God Wars it was under the control of Saradomin, but came under attack from Zamorakians as shown in the same cutscene.
- The Demonic Ruins in the Wilderness differ in size when compared to the building shown in the Ritual of the Mahjarrat cutscene. This may be due to parts of the building being destroyed and rebuilt due to heavy damage during the wars, or it may simply be a mistake by Jagex. It may also be due to the scale theory.
