Altyria Medieval is a passion project built around a realistic, but still stylized, fictional medieval world set in the pre-gunpowder middle ages. The build style leans into Minecraft's natural charm, using a stripped down version of Diverging Realms' Medifault resource pack instead of going all-in on heavy textures, so the world still feels like Minecraft while fitting the medieval theme.
If you want to come tour the expansive, atmospheric world, or build a plot and work your way toward becoming a member, you're welcome to join in. Make sure to enable server resource packs so everything looks and feels right when you load in.
