I have noticed something peculiar on the forums...
Focus on the join dates
Krez joined DtK forums roughly 2 months before Squall
I have come to the conclusion:
Krezrand is really Squall's first test account that he now uses as an undercover, incognito character to spy and keep up with the goss and shit-talk in the DtK community.
Therefore: Krezrand = Squall
