It's almost comically frustrating how Konami just casually throws in connections between the various big lore archetypes; we had Duel Terminal connected to the more "generic" (read: massively convoluted and interconnected series of seemingly unrelated monsters that explicitly contains dimension hopping shenanigans) card pool via the Charmers, Dracoslayer connected to Duel Terminal via Zefra Metaltron (who still has yet to actually be explained in a Master Guide or Valuable Book!), we have World Legacy almost definitely connected to Duel Terminal because Avida and the World Gears take so many visual cues (and naming conventions if you dig deep enough) from the Qliphorts and Sophia/Tierra, and now they're just casually calling Albaz and Aluber's power "Dragon Alchemy", something that - assuming that translation is entirely intentional - ties The Abyss lore directly with Dracoslayer, and all the connections that entails. Yu-Gi-Oh card lore is fuckin wild.
