His voice over sounds like he is 30-40 years old and his base splash goes in the same direction, but in other splash arts where his face is visible (with the exception of Renegade Talon because it's supposed to be how he looked like before he got recruited by the DuCouteau Household but I don't even think that's canon anymore), he looks like he's around 20.
I be a confuse
Talon is in his 20s or early 30s. Not that confusing.
Try Xin Zhao, who should be in his late 50s to 60s or something at the very least judging by the lore (having already being an adult in the days of Jarvan II, and watched/guarded both Jarvan III and Jarvan IV as they grew), but looks and sounds like he's still in his early 20s.
Pretty sure he's in his 20s
Necrit says 24, I say 26 at least.
Rioter on twitter said Talon should be in his late 20s
