All we need is a source of food, a source of wood, some tools, probably a new ore, and a way to make an exit portal. Food and wood could be solved by the mushroom trees me and the other guy are working on. Tools and ore could be Murexium or Veridium. Murexium would be deep purple. Veridium would be dark green. Or Xenium. Xenium would probably be light blue? To contrast with Mithril? Portals require Mese to ignite, so maybe a Mese crater rarely? Or add Mese to stronghold chests? Or, maybe a ruined portal generates rarely? I need feedback, but I can add most of these features I think.
