Right before Radiant Dawn ends, it gives Ike credit for various heroic deeds but one thing I don't understand is the following.
Final words
In days long past, a young man
strode the lands of Tellius.
He was simple yet true, his deeds
brave and noble. He reunited two
races long at war,
and healed the heart of a goddess
long gone mad.
Ask any you meet be they young or
old, beorc or laguz,
of a hero named Ike and you’ll receive
a warm smile
and a tale or two of faith, courage,
and honesty.

Is it talking about Ashera, Ashunera or Yune? He doesn't change Ashera other than defeating her. Ashunera's heart is only healed because Yune merges with Ashera, not because Ike healed her. Also, Yune didn't change as a result of Ike's actions unless I'm missing something.
Anyhow, it is ironic that the apostle, who has an actual connection with Yune, and by extension Ashera and Ashunera, doesn't get credit for this.
