I enjoyed the magical theory in this story. More would be welcome.

>>Healing magic kept in ice always sold well at Kieran's shop, because they could be kept for a long time.<<

Subject/verb disagreement. I suggest changing "they" to "it" above, or else adding "items" after "magic."

>>There had been a lot of blue level mages at during on period<<

?? "at during on" ...? I'm not sure what you meant here.

>>Fortuntaely he had a friend who helped him create past sight ice<<

That should say "Fortunately" above.

Wow, what a nifty use for ice magic!
