Hey! The story is still kind of early in its stages, and a lot of details are planned to come in later or little by little. Some things have reasons that will become clearer later.
The Memorium containing most of the lore and worldbuilding is, however, by design. It's an effort to keep the story going without overwhelming people while at the same time letting people who are more interested in lore delve more into it.
Update 14, which is on Patreon right now, has also actually sped up the menus a bunch based on other feedback I've had on that. If you feel like things are still too slow after playing Update 14, feel free to let me know, and I'll take note of that feedback as well!
