Darkshade is making a custom region? I need links, Gilan. I wouldn't mind a custom region, it would be awesome if that actually happens.
Xatu, there was a discussion on legendary dungeons, click the following link if you would like to read about it. https://forums.pokemmo.eu/index.php?/topic/54589-legendary-dungeon-should-be-a-team-raid/?hl=legendary+dungeons
All in all, we might see the next region to be implemented around 2025 if everything goes to plan.
