( Max's cell )
The cell where Max was imprisoned had complete darkness.
Even if Max wanted to, he could not read the book that he had obtained from the Universal Warehouse in here unless he could manifest a small light source in here.
Thankfully for him, he had the Agni-Astra on him which although could not replenish it's energy within this mana-less environment, already had pre-stored energy which Max could use to create a small fireball.
Max controlled the power output and created a flame as small as possible for his functional use, as he needed to keep in mind that the flame was like a lantern now which was running on limited fuel.
Since he had no idea as to how long he would be trapped inside this cell exactly, Max knew he needed to ration as much as possible.
The small flame illuminated the dark cell room, and Max was able to see the surroundings he was in which he had already sensed.
