The Ink-sphere
Ink's home, and the place from which the multiverse is watched.
What it looks like
"A place that existed outside of existence itself, a vast web of interconnected strings and paintings, stretching infinitely in all directions" (ch. 0).
Each string runs to a floating canvas, and inside each canvas an entire universe plays out, like a window into a reality. Zero saw the true scope of the multiverse here for the first time.
What happens here
It is where the guardians gather, where Zero was introduced to Dream, Blueberry, Edge, and dozens more, and where he was taught to fight, to read emotional currents, and to see the worth of a small universe (ch. 1).
It is also where the alarm sounded. When the destroyers breached the outer defences, the canvases rippled "as though struck by unseen waves", their colours distorting (ch. 1).
Time here
Effectively none. The narration keeps flagging it: "if 'day' was even a meaningful concept in this place beyond space and time", and later "Months passed, though time held little meaning in the Ink-sphere" (ch. 1).
Open questions
- Whether it still stands. The saga leaves it at the end of ch. 2 and does not return.
