I had a campaign going once in which the inteneded BBEG (we never actually got this far...) was a Paragon Goblin. This son of Malaglubliyet was preparing to take over the world, and the gods wanted there champions to oppose them. To this end, Kord himself fashioned a weapon of great power: a +3 Golblindread Spiked Chain. The catch: the champions needed to come to Kords home in the outer plains to get it.
While this is an epic magic item rather than an artifact, the difference to the characters (about level 8 at the start of the plane spanning quest) was a bit academic. When last seen, they were in Svartalfheim trying to aquire the 3 rings of major fire resistance they would need to survive the next stage of their trip. The Svartalfheim Drow were interesting NPCs, too.
