The half-elf is his soul?

"What on earth is going on?" Eldrian asked again, looking at the half-elf he seemed to be. Purple eyes, silver hair, a body in between human and elf. Part of him hoped that Ziraili would come and explain things to him, however, Eldrian knew that he shouldn't rely on others. 

He had to learn how to figure out the unfamiliar on his own. 

Focusing some more, Eldrian took in all the details of this half-elf. He had to admit, it seemed like a strange mix of his human and elf selves. A mix between his real body and avatar. 

The thought was disturbing, to say the least. 

'Right, a soul is a reflection of what you believe your core to be.'  Eldrian pondered as he watched the half-elf.  'I believed it was previously just a heart because that is what I believe is the core of a person.'

'A heart obviously symbolizes emotions, which I believe is what makes us human. That, along with memories, entangled with emotions.'
