Chapter 1 is just a prologue, to set the stage; we run into Link's first adventure in chapter 2.
NOTE: “Primordium,” as introduced herein, is a powerful entity (primordial, as you might have inferred); while we don't see much of it directly, and its hand shows only in the actions of its less-powerful minions in Link's life, some attention is given to it (among quite a few others) in a related study of scaling characters' relative power levels in writing and games, titled “Superheroes: Powers and Principalities”.
As for Link's continuing adventures, there are more ideas in the works than just these chapters on AO3 so far, and I'll get around to adding them here and there over time, but they are as yet only the barest snippets and one outline — too minimal for me to include (with any dignity) even a draft form here. If you really wish to check them out anyway, then you can find them in “What evil lurks” at my Google drive:

NB: If you're wondering how to make a series on AO3, please see my tutorial “How to make and fix a series on AO3 ” (in a series with another tutorial on CSS work skins for fonts, which made that link become blue ink highlighted in yellow [assuming that your browser settings, site skin, and third party apps didn't prohibit it]; it also covers how to circle things, view fics' work skin rules, and similar such).
