Enligt Wikipedia-artikeln Äldste Scrolls är det naturligt instabilt:
The actual number and placement of elder scrolls fluctuates constantly as it is said that they technically exist and do not exist at the same time. This makes their predictions difficult to cite authoritatively because entire scrolls or entries can change or vanish as events transpire. This unpredictability has caused other ascetic groups, such as the Greybeards from Skyrim, to find the existence of the Elder Scrolls a blasphemy.
