Every item in Old School RuneScape leaves an undeniable technical footprint. When Jagex deploys weekly game builds, data-miners inspect cache archives, item identification numbers, and drop tables within minutes of server reboot.
Independent databases including the OSRS Wiki, RuneLite item manifest repositories, and crowd-sourced loot trackers show absolute zero presence of an "Arkan Blade." Neither the Colosseum, the Moons of Peril, nor the Hueycoatl drop tables list any such entity. Jagex developers maintain a strict public polling charter and design blog cadence; weapons never enter the game unannounced without extensive beta testing, blog breakdowns, or clear quest reward unlocks.
Players who believe they saw an "Arkan Blade" in a loot showcase were almost certainly looking at an altered client, a private server build, or a renamed cosmetic override.
