Alran is a non-player character found in the Fist of Guthix lobby. He, like Getorix and Pontimer, has a theory about how the Fist of Guthix cave was created. He only knows for sure that it is called Fist of Guthix because Fiara mentions the term occasionally.
Alran's theory
Alran's theory on how the Fist of Guthix cave was created is that the cave was created by Guthix during the God Wars as a test of people's strength. He lets people go into the cave because "it wouldn't be balanced otherwise." He regards Pontimer's and Getorix's theories as nonsense.
