So a few questions:
- Comments on 4E artifacts, or lack thereof.
- Your favorite book or source for artifacts.
- A list of all D&D related artifact books.
(The reason I ask is that my group is currently 9th level and I'm thinking about what Paragon Tier will bring and I'm wanting to integrate a major artifact at some point, possibly sooner than later).
Also, I realize I didn't really actually answer any of these questions, so...
1) There are definitely artifacts there, but they are floating about in various places - Dragon Articles, DMGs, setting books, planar books, monster books, etc.
2) There have been some cool ones in Dragon articles and in various adventures. They also ran a contest to see fan versions of Blackrazor, as seen
here, and the first entry there is pretty awesome. Still, my advice would be to figure out what artifact or type of artifact would best suit the plot of the game in the Paragon tier. If you know a bit about what elements the game will involve, people might be able to steer you towards the most appropriate choice. Or, worst case, help you stat out something unique for your game.
3) Ok, probably not comprehensive, but... (Paragon artifacts in Bold):

There might be some more out there hidden about in adventures or articles, though many of those are specifically tied to the plot of the adventure.
