Reveal: Index & Codex
by Nking20
Reveal: Index & Codex lets players uncover hidden records using materials configured in-game, and stores them in shareable Index Books for story and lore content.
What it does
Reveal provides two main tools. Using materials set in the config, the Reveal Codex lets a player bring hidden records to light, and every record the player has found is kept in the Index Book.
A page-style reading screen sorts a player's discovered records into categories for browsing. Index Books can be shared between players, so another player can read, use and merge the records a friend has found, which lets story information spread through multiplayer play.
Reveal runs on NeoForge for 1.21.1 with client and server environment, so both the server and every player need it. It is released under All rights reserved, so the code is not open source, and public links exist for the wiki.
