Thanks for the links. I didn't realize there was that much early artwork still around, other than Marian's
website (GFX section).
The archive of Kiya's
site has a lot of the in-game art (under 'Quests' and then 'Rune manuscripts').
In the backstory of DD, during the previous war with the Lord of Chaos, he forged a sword for the archmage Ulthring, leader of the army. The sword was imbued with a fragment of the soul of the Lord of Chaos, making Ulthring much more powerful. After the Council of Seven sacrificed themselves to banish the Lord of Chaos, another archmage used the sword to finish off Ulthring, still alive after an earlier arrow to the eye. The sword slowly started taking over the mind of the archmage, and before it could gain control he lock himself in the Stormfist castle treasure room.
In DD when you explore the treasure room looking for the Sword of Lies, you find nothing but a child's toy, left behind by Janus after he found the sword and was easily corrupted by it.
