The procedure through the station went about as well as could be expected, to Cain. It was when Benjamin so sharply entered the Commander's room and just burst with an annoyed attitude to get this out of the way. Cain easily guessed that he didn't like the Commander, but this was rather uncalled for.
"Er, excuse me for this," Cain seemed to apologize for being a part of this heavy interruption as he stepped forward. With a steady breath, he began, "I am Cain Alabast. I am a sort of archaeologist, and a basic duelist myself. After hearing about the recent matters with the so called 'Cult of Shadows', I-" Cain hesitated to continue as the chief sighed notably in irritation. "...Well, the Cult has been making inscriptions on the Prime Pillars. I figured that if the rumors regarding the Cult's intentions were true, then these inscriptions could possibly connect all the way to the ancient Shadow Games, where the Duel Monsters game has drawn much inspiration... from."
The Commander was obviously bored and sick of this explanation, it probably being something he's heard before in different wording. Cain had to rub his temples a bit to maintain his composure; he could definitely see where Ben's dislike to this man came from, but Cain wasn't going to give up.
"Long story short, the inscriptions do indeed connect back to the Shadow Games," Cain said with a bit more force and speed, trying to better hook the Commander's attention. "It would appear that, when such inscriptions are put on an obelisk like the Prime Pillars, then someone, with the proper ritual, could actually use the Pillar to call forth a pocket of the Shadow Realm." The Commander twiddled his pen with no more interest than before.
"I know this," Cain said yet more seriously, "because just today, two Cultists approached Mister... Castellar and I, and preformed such a ritual in order to challenge us to not a duel, but a Shadow Game. While in the Shadow Realm, all of the the cards in Duel Monsters become real monsters and spells. And whoever loses such a Duel, loses their life," Cain emphasized.
"When we defeated these Duelists, there was nothing left of them." Cain motioned to Ben to had him the confiscated Duel Disk. When he did so, Cain held it forward to show it off to the Commander. "Nothing but this." Cain made a show of pointing out how the Cultist's Duel Disk was very literally scorched and scratched in many places. "If this is what the Cult of Shadows is capable of doing, having them inscribe all of the Prime Pillars may allow them to pull the entire city into the Shadow Realm."
Cain finished with that, resuming an idle stance and waiting for a reaction.
