Overgrown’s Origins

Origins lets every player choose a species when they spawn into the world, each with its own strengths, weaknesses, and playstyle. Every origin, power, and layer is data-pack JSON on top of Apoli, so servers and modpacks can retheme the defaults, extend them, or replace the whole roster without writing any Java.

Not a fork

This is an independent, from-scratch implementation of the origins concept. It shares no code with any earlier mod of the same name. It is written against Mojang’s Codec DataFixerUpper serialization API rather than hand-rolled Gson parsing, and is built for Fabric 1.20.1, Fabric 1.21.1, and NeoForge 1.21.1 from a single shared codebase.

It does read the same data-pack format, deliberately: the JSON type ids, field names, and the origins: namespace are all still accepted, so existing origin packs and add-ons work here without being rewritten. If you have used an origins mod before, your packs and your muscle memory carry over but the engine underneath is new.

11 origins ship by default, plus Human

Features

• Origin layers that lets you group origins into independently chosen layers (species, class, bloodline, anything), each with its own selection rules and data-pack merge behaviour.
• A choose-origin screen with seasonal re-theming built in.
• Badges, tooltip icons that call out a power’s extra behaviour (keybinds, recipe unlocks, and more) at a glance.
• The Orb of Origin, an item that lets a player re-roll their origin on demand.
• A built-in randomizer that can re-roll on death, on sleep, or on command, with an optional “lives” counter. No separate add-on needed.
• Origin transfer to steal, give, or copy an origin between players.
• Full multiplayer sync, including players who join mid-session.
• /origin commands to get, set, check, and randomize origins and layers.

Requirements

Requires Apoli, the power engine this mod is built on. Fabric builds also require Fabric API.
