The Chapter 1 and 2 Dark Worlds have their NPCs spread across three pages. This leads to most of these pages only having a few NPCs. They could easily be merged into "Card Kingdom/NPCs" and "Cyber World/NPCs". These pages wouldn't be too long, and would be around the length of the already-existing Hometown/NPCs.
Hometown/NPCs is huge though. We had to shorten that page several times, it was so long and filled with infoboxes that upon the wiki’s release it constantly caused the link refreshing job to fail every time it was edited. If we can avoid having an NPC page the size of Hometown/NPCs, I’d prefer that.
For scale, all Card Kingdom NPCs in one page is 21296 characters long, Cyber World is 21072, while Hometown is 36914, so these new pages would be substantially smaller.
