Aw yiss, inventing us some headcanon draenei lore! Observant readers may remember that we alluded to these personal symbols back in Vid’s character profile.
If you look at official WoW artwork, there are TONS of different draenei sigils/symbols depicted. Why ARE they different? Do they represent different magical abilities? Or is it like we’ve described here, something biological, like an individual’s unique DNA footprint?
Personally, I think it’s a lot cooler to imagine those symbols as displays of personal identity rather than just to indicate “I’m using magic.”
