Preliminary anatomical drawings for next year’s Guide
Fungi from Yuggoth: Concept art, sagittal dissection of the “cerebrum” showing basal ganglia and ichor vessels and brain cylinder concept.
The idea behind the brain cylinder is that they’re actually living Mi-Go that have been modified to develop without a brain. This strain of creatures are basically shells meant to help keep the extracted brain alive, allowing it to experience the world through the atrophied creature’s sensory organs.
When traveling, the creature could be replaced by an artificial (mechanical) cylinder like the one from Whisperer in Darkness, but this one would be far more limited than the biological host.
