Dino's Guide to Ultima VIII - Pagan
After the end of Ultima VII Part 2: Serpent Isle, the Guardian's hand
reached through the void and grabbed the Avatar. His hand emerges from a
pentagram in the sky, on another world. The Guardian taunts the Avatar,
then drops him into the ocean below. While the Avatar is busy trying to
survive in a world where nobody knows who he is, the Guardian is free to
take over Britannia and Earth.
As luck would have it, the Avatar is subsequently rescued from certain
death by a fisherman near the docks of Tenebrae.
