Lorel was indeed meticulous and cautious. The victims he chose for the charnel rite were carefully selected based on four specific criteria: A) they were newcomers to the frontier; B) they hadn't formed any meaningful connections; C) they lacked powerful backing; and D) they were not strong in themselves and couldn't put up much of a fight. This approach ensured that their disappearance wouldn't cause significant ripples. Even if an investigation was launched, it would likely be short-lived and attributed to devil's work, given the lack of clues.
Despite his careful planning, Lorel couldn't shake off the fear of getting caught. So, after performing the rite, he faked his death and lived under a false identity outside the frontier. Only after years, when he felt the coast was clear, did he dare to return. But even then, he didn't rush to the secret basement to claim the Uglyface, fearful of traps. Instead, he disguised himself as a weak bloodline user who was a painter.
