No, he grew up in Vacuo, implying he was born there. He even says in Butning the Candle "Hey, I may have moved to Mistral, but I grew up in Vacuo. It's not exactly a shirt-and-tie kind of place." He calls the sand dunes his home turf in New Challengers when facing off against NDGO due to Vacuo (where NDGO is from) being a desert kingdom, and in Menagerie Sun and Blake share this exchange:

Sun: What! You guys have that much more space? Why waste it? A little desert never hurt anyone!

Blake: It's not like the desert in Vacuo, Sun. The wildlife here is more dangerous than most other regions.

He is shown to be a Vacuan through and through who moved to Mistral to enrol in Haven.
