Now that I think about, building novel technology kind of runs in the Kalos royal lineage, no? Be it doomsday weapons, mass longevity dispensers, or holographic communication systems
I don't think it would be too far-fetched to assume L would end up building some landmarks of his own as time goes on (and he has a ton of time, I theorize that more than AZ)
It would be cool if, say, to contrast with AZ's general penchant for WMDs and things that destroy or break natural order, L built things that preserve it, eg. a giant greenhouse for the inevitably polluted future and preservation of organic Pokémon (Garden of Eden or Ark of Noah, anyone? I promise this isn't an Aether Paraidse ripoff) ...
...bear with me, there's simply yummy contrast and parallelism in here 😔
