However, the greatest atrocity by far that is attributed to Lord Reson would have to be the events of the Vision Wars, which took place from Age 566–Age 568 and was carried out by the division of the Arcane Order known as Cosmo'rath, led by the Xoultac (Pride Archfiend) known as "Evil Ninja Emperor" Heinrich, who was even more evil and brutal than Lord Reson himself and used methods that not even Reson would approve of, such as attempting to wipe out an entire species of humanoids (and very nearly succeeding) and irreversibly corrupting (almost) the entire population of another race into mindless monsters through torture and dark magic. Heinrich was in possession of two artifacts apparently created by Lord Reson, the Film Reel of the Cosmos and the Projector of Conjured Realities. Together, these two items could send one from the Nava–Verse to Earth (and vice versa), which is impossible under any other circumstances. Heinrich used the items to visit Earth in human form, and there he met Connor Thorn, who got in the way of his antics there and thus was sent to the Nava–Verse in retaliation, where Heinrich thought he would die. This would prove to be the Xoultac's undoing as Connor Thorn's last name happened to also be the name of an alleged "Messiah" said by the Next Testament to stop the evil attacking the Prime Galaxy during the Vision Wars, and even though Heinrich had secretly already killed the real Thorn, Connor Thorn survived the predicament he was thrown into upon being teleported to the Nava–Verse and went on to kill Heinrich, ending the Vision Wars, thus becoming a messiah in his own right. Connor Thorn, now known as just "Thorn", vowed that he would do everything in his power to one day destroy Lord Reson, who he and his allies believed to be just as evil as Heinrich
In Age 809, Lord Reson was intercepted while traveling through the Gomorran Desert Plane and attacked by Connor Thorn with an elite strike team. All of them including Thorn were killed by Lord Reson, though the details of the battle are unknown.
Lord Reson is largely viewed as a pure evil monster and considered an "Abomination" (which is a technical term in the Nava–Verse) by mortal followers of God (who tend to be quite simple–minded), especially due to Heinrich's actions, but in reality there is much more to him; however these hidden depths of his cannot be revealed yet as they would spoil major parts of the ongoing saga of the Nava–Verse.
