Constantine VI had always been skeptical about the authenticity of the letter.
The letter had been verified by a host of bishops and pastors, and indeed, the handwriting matched that of the Prophet's, undoubtedly penned by his hand.
However, Constantine VI, steeped in imperial politics for years, could not help but consider the possibility of forgery.
Indeed, Constantine thought so and doubted that the letter was genuine and really from the Prophet's hand.
The letter seemed quite reasonable, but on closer inspection, there were many persistent doubts, particularly when combined with the prior incident of Veldor and Pastor Casas seeking the Queen's mercy, it was hard not to arouse the skeptical Emperor's suspicion of the letter's authenticity.
Even with his suspicions, Constantine VI had no sufficient evidence to definitively declare the letter false.
Therefore, he dared not oppose a public trial.
