If Karako truly turns out to be a Lord of Mind, would it be safe to assume that stunted growth plays a role in a Lord's life? He seems to have that in common with Caliborn

Caliborn embodies the Yaldabaoth of Homestuck- A Deity unable to see the World of Ideas and who considers himself the true and absolute God. This in itself ties Lordship with the idea of stunted growth- However it’s not the only thing, as it also plays a big part in The Neverending Story, from which Homestuck draws a LOT regarding the Lord-Muse roles, and other Media have showcased Yaldabaoth-like figures by that same inability to grow beyond.

So it is not that it’s just a Lord-like trait, but rather, that the Lord’s ties with Gnostic deities, Godhood and the references it draws from feature Stunted Growth rather prominently. Whether ALL Lords do or it’s just a good reference to toss in, we’ll see if Karako’s ever confirmed/deconfirmed to be a Lord or Not in the future!
