The Return of Luke Castellan- a Lukercy fanfiction

Chapter5- The Lost Soul

(This chapter is in Luke's pov.)
The next day after Percy had said yes to being my boyfriend, we hung out for a few hours before Percy had to go train a few of the campers in sword fighting techniques. While he was training the campers, I walked around the camp trying to get used to being back at camp again. As I was walking around the camp I noticed some of the other campers staring at me and whispering to one another, they were probably whispering about me because I heard one of the other campers mention my name and the words 'traitor' 'untrustworthy' as well. This made me feel angry, but I chose not to interact with the campers and walked away. I was walking still, when I felt this phantom pain near my left armpit, where I'd used the 'cursed blade' to stab myself to defeat Kronos. I didn't know what the pain was, but it hurt. I looked around to see if any of the other campers were watching me, when another burst of pain hit me, I stumbled slightly walking over towards a tree where I sat down.
My left armpit felt as if it was burning, I quickly pulled my shirt up and glanced at the left armpit where there was a slightly faded long scar. It was still visible, nothing looked as though my scar was burning but it still hurt. I pulled my shirt back down and looked around, wondering what was happening.
I knew something wasn't right with me, I knew that my soul was somehow gone or missing. I must've been sitting down by the tree for more than a while, because around mid day Percy came up to me looking worried. He sat down beside me and looked at me. "....Luke, what's wrong?....you look pale..." I shook my head to clear the fog in my brain and turned towards him. "....my scar, the one I got from the cursed blade is hurting, it feels like it's burning but when I looked at it, there wasn't any evidence of it burning...." He went silent and looked at me. "....do you think this pain is or might be related to your soul being gone?...." I went silent at this, as I looked away.
I didn't answer him, just looked away trying to think. I remembered taking the curse of Achillies, by going into the river Styx. I remembered almost everything that I'd done as Kronos, including when I stabbed myself in the place that I'd chosen as my achillie's heel, the part of my body that if stabbed or injured would kill me. I was silent for a few minutes then I looked at Percy. "....yes, I think the pain I'm feeling is connected to my soul being gone....we need to find out why or how it's missing...."
He nodded, looking at me still. ".....Chiron said that you should go to the infirmary in case there's anything wrong...." I nodded, glancing over towards the Apollo cabin (infirmary). "Alright...." I stood up slowly and looked at him. "....i'll come and find you after..." Percy smiled, and nodded before he kissed my cheek and walked away. I smiled to myself at that, and turned around, heading towards the infirmary.
(In the Infirmary)
I walked into the infirmary and looked around, there wasn't many people there except for some of the Apollo kids. One of them noticed me at the door and came up to me. The kid stared at me silently for a moment. ".....Luke Castellan, right?..." I nodded slowly, hoping that I wouldn't be called a traitor or anything like that....the kid glanced over at a few of his fellow cabinmates before looking at me. "....my name is Heron, is there something you need?..." I was quiet for a moment, wondering what I should say. "....i need to know if there's anything wrong with me...I have this wound that's hurting but not visibly....can you help?." Heron looked at me silently, I waited for an answer. "....yes, we can help....sit down over there and we'll see what's wrong..." He pointed over to a cot/medical bed, i walked over and sat down and waited.
A moment later, Heron came over and using the medical equipment he did a doctor checkup on me. After this, he used his 'Apollo power' to examine me. When he moved his hand near to my wound the glow from his power went red. Heron stepped back, and looked at me. He frowned, clearly uneasy. ".....Luke, physically and mentally you're healthy. But it appears you've lost your soul because you were the bearer of the Achillie's curse, but when you mortally wounded yourself to destroy Kronos, the curse took your soul away once you were revived...." I went silent as he said this, and looked down at the floor for a moment. ".....is there anyway to get my soul back?...." Heron looked at me silently for a moment. "......Well....there is one way to possibly retrieve your soul....." I looked up at him. ".....and what way is that?...." He went silent, very silent for a moment then looked at me. "......You would have to travel to Hade's and ask him to return your soul..." I froze and looked at him. ".....Ask Hades?....that's....he doesn't do anything for free....i would have to make a deal with him...." Heron nodded, putting away the medical equipment. "Yes..." I sighed, knowing that if I told Percy he'd immediately tell me not to go ask Hades for my soul back. But I had to. I thanked Heron then left the infirmary and went to find Percy.
