Well, chances are that I'on won't actually have to fight even if he joins the scene. Presuming that you haven't been keeping up with IC events lately, Blue (full name/title Blue Tool, unique secret special forces agent assigned directly to the Blue Duke's service) fought Ixion and Morgan in an alley because she mistook Ixion for someone else, and during this fight she both unleashed magic that created an extremely bright lightsource and, upon cancelling that spell, switched to a much less visible version of this that focused all the light into what was essentially a powerful laser, which would unleash a significant amount of magical energy. Since then Blue was killed by the Fixer (the person she mistook Ixion for, the right hand servant of the Grand Master) and though Ixion and Morgan nearly got in a fight with him, too, they decided against it due to Ixion realizing he was a fellow servant of the Grand Master and both of them realizing that the Fixer is quite simply far beyond what even the two of them could handle together. So now the situation is already kind of resolving itself, and its natural point of progressing onto a different matter is relatively near.
