iirc, Artifacts with powers are part of the magic arc.
I'd just like to see them treated like characters in the histories, with a history of their own.
One thing you'll find in myths is artifacts wanting stuff. Wanting to be found, wanting a new owner, wanting a certain type of owner. This isn't just the ring of power, it's other stuff too.
You also see them abandoning wielders.
All this means that modeling the artifacts as characters with goals kind of works.
Sure, once you flip over from historical time to real time, their sentience kind of goes away, but it ensures that at the end of the histories, each artifact has a story and is in a reasonable place (not laying in the woods somewhere). Quests would naturally attach to them. Rather than the simple go kill this, you'd get a 'go get this back' quest.
Imagine starting the game in a town, talking to people, and finding out that 300 years ago some badass warrior killed 3 dragons with Ul Argathin. 'Interesting' you say, I'd like to get that sword! So you go traipsing around the world, tracking down the warrior. Until you find he was killed by the goblin invasion of 452.
You proceed to the goblin civ, where you sneak in, killing a few goblins, and reading the crude legends painted on the wall. Finding one of Kabdash the Great carying the glowing firebrand and being struck down by a GCS sends you off towards the cave where he fell. Unfortunately the only way to the cave is to fight through 3 miles of monster infested tunnels.
Deciding you need some help, you retire the adventurer and build a dwarven fortress near the cave. Sure the monsters make the fortress a nightmare, but you build up a decent military force and retire the fortress.
Reactivating the hero and using the fortress guard as backup(recruiting, or just straight up MMO pulling) you fight your way through the cave into the inner sanctum of the GCS. Where it promptly rips you into six thousand pieces before you even lay hands on the sword.
Long story short, items in the history would be cool, especially if they are artifact level and give your adventure characters something to do
