History
The Doctor visited Metebelis III at an unknown time period, during which time he stole a crystal. (DW: The Green Death)

At some point in the far future, a Human starship crash landed there. Humans and sheep survived the trip, as did some spiders. Over the course of millennia, the crystals mutated the spiders into the Eight Legs. The Eight Legs enslaved the humans and proceeded to harvest and eat them.

The Eight Legs planned to take over the rest of the universe, but required all of the blue crystals. The Doctor's theft of one of the crystals caused the Great One to retrieve it. The series of events which followed led to the replacement of the crystal which flooded both the body of the Doctor and the Great One with radiation, which caused the death of the Great One and the regeneration into his fourth incarnation.
