A Seed.
Something they had known all their lives as they always had their own perceptions of such entities- noen of them being positive!
Seeds were ignorant Lifeforms living in Existential Domains, their lives always capped to a certain level they could never rise above of.
Their records were boring to look at, they lived, they died, and they were quickly replaced.
They contributed to the purity and accumulation of Vitalis and Vacuous as this was the main purpose of their lives.
To be Seeds that would eventually make way for more Fruits of Existence.
From the standpoint of a Basileus belonging to any Legacy, a Seed was akin to an ant they could step on if they so chose.
Akin to the clouds beneath their feet.
They could be stepped on, they could be sat on, and they forever remained beneath them.
So to actually have a Seed appear in the Archaeos Vitalis Pylos…
Truly, it was a violation of existence itself!
