So i may have a theory about the former warrior of light.

I went back to discuss with Urianger,and he told me something very interesting:
He said that Louisoix probably used the power of Althyk to send the warrior of light in an other dimension,that they were riped of from their reality explaining why no one can remember what they look like,and then,we see that the warrior of light took the side of Ascien.

Now the question,did louisoix send the warrior of light into the Ascien realm,because he know something about hyadelin that we dont know ? Does that mean that in fact,the Ascien are not the bad guys we think they are ?

And one last thing about Ascien that i think about,the first time we discussedwith a AScien,he told us that we could see him beacause of the Echo and because we must be aware of them to be able to see them,so their form must change depending of how you see them,so do we see them shrouded in darkness because we were told so ?
