I'm glad I'm not the only one who not only picked that up, but also thought of it in that way. Sadly I don't think we'll ever get an explanation. The only other time we see something hurt someone or make them uncomfortable is when Ryne and the WoL get that water blessing from Runar.

This does give some weight to another theory of mine in that the shards are like a PH scale and that each shard has their own ph scale. In that the 1st obviously is closer to the light and the 13th darkness. Along with both and light and darkness seeping into everything.

Thus the reason why on the 1st Ardbert and friends found it very easy to defeat darkness and why those of the 13th had to use auracite.

So, we're guessing that Asahi wasn't a shard of Fandaniel and one of those rare instances where they slapped the memory of them into Aahi's body along with possible personality seeping. Kind of wished we could have seen a little more in how the Ascians behaved over the years or even during the earlier parts of the game to see if there really is any or if this was a botched raising.
