Tear of the Seas

The Tear of the Seas is one of the five fragments of the great Blackrock Obelisk of Pagan. It is Hydros's object of power. It appears in Ultima VIII

Description
When the Obelisk was shattered by the Guardian, the Tear of the Seas fell into the sea itself, where Hydros found it and stored it safely in one of the drowned cities of Pagan, guarded by her undead minons. It stayed there for many centuries, until one day Devon found it in one of his fishing nets, and kept it - most likely his yet undiscovered powers of Tempestry played a role in this strange event.

Devon gave the Tear to the Avatar when the hero asked for it after being made aware of its existence from several books after killing Malchir. It was used then to overpower Hydros. It merged with the other fragments to recreate the Obelisk.

Trivia

 * Originally, the Tear would have been found from an underwater city of Hydros, but the city was removed from the final release. See Plot Cuts in Ultima VIII.
