This implements Old City, the Honey Grandma's House, and its Pokecenter+Mart. Bunch of other bits and pieces not added yet, need to figure out the lore for them.
Honey Grandma is designed to make it easier to get important Pokemon, rather than give access to anything new. Thus, she's Nihon-locked by being an Old City resident. Martha's Perfect Rod will follow this trend.
Gold Berry tree exists to make them renewable in-game, I think this is very important.
The flypoint seems bugged.
This adds the Pokemon Centre infrastructure for Nihon and Silent Hills's one.
For all future Nihon Pokemon Centres, they must refer to the 2F one for the warp, and the map blocks for 1Fs should use the Nihon variant.
Kanto will follow suit (eventually). The aim is to make a more immersive region structure.
