Ultima VII Part Two: Serpent Isle - The Silver Seed/DeathWatch Keep

Upon your arrival, head north into the Banquet Hall and talk to the cloaked automaton. He proclaims you the Champion of Balance. Be sure to use all the conversation options he offers, and eventually he'll give you a magic keyring.

This is a very useful device. It makes hunting for the right key obselete. Once you have it simply press "K" and click on a door or chest, if you've added that same key to the keyring the lock will open! What's more it will never become heavier or take up more space as you add keys to it. To add a new key merely drop it onto either the Avatar or his HUD icon and it will be absorbed into the keyring. Sometimes keys refuse to be absorbed automatically, which means you'll need to double-click them and then use them on the keyring. The only keys that will never fuse with the keyring are the Keys of Fire and Ice, because they instead fuse with each other. After they have done so, however, you can then put the resulting Blackrock Key onto the keyring.

Isstanar will also tell you that to prove yourself as the Champion of Balance you will need to acquire four magic Orbs from the surrounding dungeons. However legions of Chaos monsters lie between you and the Orbs, not to mention an array of puzzles.

From here you can go to one of several locations:
 * Abandoned Outpost and the Red Orb
 * Issik's Maze and the Purple Orb
 * Aram-Dol's Lair and the Blue Orb
 * The Fiend's Lair and the Golden Orb

Once you have all four Orbs, you can finally retrieve the Seed.
