Jeweled Weapons

The Jeweled Weapons can be obtained in Ultima V in Windemere, after joining the Oppression, from Thurd. He demands the password of the Resistance for them. But it isn't worth this, since the weapons are u.s.e.l.e.s.s. They don't even do one point of damage! What a reward for destroying the resistance against Blackthorn's regime!

This is only a good lesson that in the end, siding with the tyrant Blackthorn will only give you pain, loneliness and treachery as reward. (Therefore the Avatar stayed away from these, and it isn't written down as a story)
