The Shadow rolls a 6.
AIiCE rolls a 6.
AIiCE grasps her fiber and ports away as the Shadow seeks to eat the light of her avatar.
The advent of Durin's ultrabright light does not blot out the Shadow. The shadowseed is not vulnerable to the light it feasts on, but it must be the one to make an advance if it is to benefit from its feast. Therefore, once AIiCE is out of its grasp, it leaps to the fission-powered bulb intended to arm the trap. Soon the light grows dark, and the Shadow increases by only a tiny fraction.
If the Shadow is to become truly sizeable, an immense amount of light will have to be destroyed.
As you gaze upon the gorging shadow, you notice it is slightly less disc-shaped than before, as if the higher-dimensional object projecting it has shifted just the slightest bit. The imperfect impression distorts accordingly. The shadow is not mindless - it is capable of choices relating to its goals, and its shape is apparently tied in with some other entity.
