Something I keep noticing about artifact lore is that it’s rarely linear. Reading from Flower of Life to Circlet of Logos is never going to tell you a story from beginning to end. And even if you try to piece them together in the right order, you never really know if you’re doing it correctly or not — there could be pieces within the description for one artifact that are told out of order.
Some artifacts tell stories of things that haven’t happened yet (I realized this when revisiting Husk of Opulent Dreams after we progressed through Scaramouche’s story more), so we can never really assume what has happened when. Some sets, like Resolution of Sojourner, do help fill in the gaps for events we know have already occurred in Teyvat’s history. On the other hand, who’s to say the Berserker isn’t someone we’ll encounter in the future?
