What would happen if Lord English just, didn’t exist?

The ramifications would span all the way to the beginning of Homestuck. It’s very likely the Kids wouldn’t have even existed, and even if you just did the story as it was but removed LE, the entire plot would’ve been radically different.

Or, not. See, the thing about Lord English is that, he’s a Symbol. A lot of things in Homestuck are teased and talked about. They have roots in some sort of concept- Like a Yaldabaoth, and as the story goes on, Hussie developed such concepts. So, without Lord English, the story would’ve been radically different… But it could have also been the same, because without Lord English, Hussie would’ve made another figure to fill in the spot of the Yaldabaoth of the story. Different Twists and Turns, but ultimately, a similar threat with a similar end-game state.
