Now we know that summons are nothing but shades of the real gods of lore...
So...in fact...people can summon whatever the hell they want as long as it has some belief in it...

So now tell me..whats stopping the scions or the 3 generals...from actually performing a summon to bring the warrior of light?

Think about it...just like iceheart summoned shiva into herself...what if they were to summon the warrior of light into ourselves?

Barring the negative side-effects it would have on the land of course.
