Thank you :)

I discovered the pentatope in a deep dive on research on Tesseract's. The standard 16-cell honey comb Tesseract has an alternation in 19 cells, which i figured could be a tesseract-19. The pentatope (or 5 cell) corresponds to the 16-cell in the a and b series respectively, so seemed the best fit for working like a key. That said, hours of wiki, probably got myself rather confused.

Also, totally didn't get the sprout/plant part. Somehow i read it as spout, with the sea part, and was envisioning a puff of green rising from the sea of black sand in the distance, as like, shudders from the inter-dimensional monolith. And spent a good few hours trying to figured out the 'bathed a leaf' in the end, figured it was something lost on me, focusing too much on the details with a mind wipe out. Concluded it was to with turning over a new leaf, a new start. Damn it, first one back and done it again!
