In the first IB, the God King stabs siris with the Infinity Blade. Since, he was believed to be a mortal in IB1, its understandable that he died and his bloodline trying to get revenge. But, after IB2, it is revealed that he is, in fact, another Deathless.
It is clearly stated at the end of IB1, that the Infinity Blade has the "ability to prevent immortals like the God King from resurrecting after death"
My question is this: If Siris aKa Ausar was indeed a Deathless, shouldn't the Infinity Blade have killed him permanently in IB1 itself? Or am I missing something?
