Landing in Oman as a man wanted by the Royal Family and trying to get through its customs was pretty much a suicide mission. It was an absolute fool's errand. One that would normally no doubt result in one's death.
That being said, Alex was a master of disguise, no doubt in thanks to the rewards the system had granted him. Because of this, Alex had the ability to peerlessly walk through any security checkpoint with a false identity.
Thus, the moment Alex's plan landed in the Capital of Oman, and the security checked his passport. This time going under the guise of Roland Beran, a citizen and businessman from the Czech Republic. Alex once more managed to get past the security of a potentially hostile nation without eliciting the slightest suspicions from the authorities.
