[W]e’ll be adding a glossary for players who begin playing from Patch 6.1 or later. Even now, for example, people who used a Tales of Adventure item may be thinking, “Wow, why is Alphinaud so outgoing all of a sudden?” which is the kind of confusion we’d like to avoid. Glossary entries will be added automatically as you progress through the story, so you won’t need to go out of your way to collect them.
The Unending Codex is still in the planning phase, but within the next ten years, we may eventually need something that allows people to play the game without starting from the very beginning, which is what we’re preparing for with this feature. If possible, we’re hoping to include entries on important lore concepts such as aether and the six elements.
