Here are some sketches of those walking echinoderm creatures he's been talking about. He's drawn these before, but these sketches are a little more detailed.
Text next to the walking starfish on the top:
"This starfish appeared to be a mobile transport for a colony of edrioaster-like beings. I believe they were sentient, for they seemed to interact with each other via waves of their tube-feet and flickers of prismatic cilia. I don't know if the transport-starfish was intelligent or merely a beast of burden."
Text concerning the walking brittlestar on the bottom:
"The central body has light-sensitive plates that together function as a single giant eye."
"Many of the starfish-beings I have met have these 'compound eyes'. "
"This one I believe to be part of a 'worker' group. Though I don't know if they have castes like ants, or if they are more mobile socially."
Here's a drawing about the walking urchins and those weird organic helicoplacoid-like data-storage devices he mentioned.
Text on top:
"Another denizen of the city. A walking sea urchin. I believe it is sentient."
"The sentient urchin seas (sic) through its tube feet. Each tube foot is a simple eye."
"The being walks on elongated spines on its underside."
Text on the bottom referring to the helicoplacoids:
"I saw a vast meadow of these structures. The Astarapomp told me these are
"I saw many of the balloon weeds growing amongst them."
"They resemble helicoplacoids. Is it convergent evolution?"
Helicoplacoids, by the way, are an extinct group of spindle-shaped echinoderms from the Cambrian period. You can read more here.
