Deciphering Kroll's ancient menace from tribe history

The illustrated tribal history serves as the central artifact revealing Kroll’s cyclical awakening pattern and dormant periods. The Doctor uses it to deduce Kroll’s massive size and imminent return by interpreting the footnotes alongside the dramatic illustrations of previous manifestations. Romana notes its 'happy ending' for the third awakening despite the text’s actual grim content.

Before: Stored in the depths of Kroll’s Pit, undisturbed for centuries, in possession of the Swampies as a sacred but poorly maintained record.

After: Flung back down the shaft by the Doctor in a moment of urgent realization, destroyed or lost in the cavern below.
