The godseeker, who was seeking radiance is overtaken by void after you kill it, and the infection fades. If you have the flower, the flower contains the abyss seeping from his body, if you don't then the abyss escapes his body. Either way the infection has ceases letting the hollow knight free from the temple of the black egg, and that's who meets hornet at the end
Or that's my take at least

I figured as much too, though like, where exactly did the godseeker actually go? It’s hard to believe he actually went inside the flower. The whole flower thing is really weird, especially since its powers are never directly stated.

Then once you got the simple key, go down to the Royal Waterways. Go down into the sub area that leads to the Flukenest. Turn left when that explosive bar thing is. And at the upper left corner, break the ceiling.

Once you do so, a new subarea will open, leading you to the Junk Pit where the Godseeker lies. Use the simple key to unbind him, and then the dream nail to access the actual content.

Ok I know that’s a lot to take in, so just watch a video or the wiki if you’re stuck on something.

Almost . I just need to beat Nightmare King Grimm and the Radiance

Good luck. I just banished Grimm because two masks of damage is too much.
