Kingdom Hearts: Child of the Sun, Part 1
''I arrived in Radiant Garden to find my fellow members Soixjah, Kyxiel, and Xac-Shii already there. No memories have been jogged yet but I have hope that it will all return. Oh, and I made a deal with Merlin to learn magic! This is going to be awesome.''
 * Galexgan's Tale 1

''Part of the deal with Merlin was to have a book that Kyxiel and Xac-Shii were interested in repaired but whe we went to the see Cid, who Merlin said would repair the book, we were told we would have to do something for him in return. A mysterious Knight in White Armor was in the chapel room of Hollow Bastion and we were asked to defeat him as payment. A man named Leon led us to the room and as we got there we could tell the room had been untouched for a long while. Leon had explained that this was because of the Knight. They had been unable to work on the room since he appeared. SO tasked with this I fought the Knight but midway through the battle, I was losing for your info, we were once again asked to do something in return for his leaving without a fight. He asked us to go in search of a Heart, well actually a Heartless. But anyway, we were supposed to trap the Heartless and tell the Knight to come so that he could free the Heart.''

''Cid fixed the book for us anyway for our effort, plus he knew we would take the Knight's quest and get him to leave eventually. I'll get to learn magic when the girls finish their research.''

Galexgan's Tale 2
''I have just arrived in Radiant Garden again. Kyxiel and Xac-Shii have finished their research with the book and can now return it to Merlin! He promised to teach me magic once we returned the book so here I come.''

''Merlin taught me magic, I apparently caught on with ease. It was pretty easy now that I think about it. Anyway, now that I have magic my quest will be alot easier.''

Galexgan's Tale 3
''We chased the Heartless back to Hollow Bastion, right into the arms of the Knight. After the heart is released the Knight has a revelation, he realises that the heart belongs to me and tells me that he is my great-grandfather! He tells me he participated in the Keyblade Wars and was brought back to life to apparently help me regain my heart. I can't believe it! But it does seem right... And so I take it to be the truth. I told him I had to go now though... I have to report all of my findings to Sulcax... I wonder if anybody other than me has realised how angry he's gotten lately?''
