Secati

Secati were created by accident, when some distant humanoid species were experimenting with magic and it's influence on them. Their researches led them to point of no return and caused unpredictible results of creating new sentient being, which they imprisoned and researched. What they didn't know was, that their deed resulted in iterations of same being starting to appear all across the other worlds, these anomalies only growing in numbers as they experimented on their captive, unkowingly creating a whole race out of its confusion and pain. It was angry and painful crying for help. Some sort of unconscious call.

A call that was soon to be answered...

Now, Secati are still appearing on every worlds possible - being the side effect of magic abnormalities of first Secati suffering. When the anomaly is arising - Secati are popping out of them and dropping into existence to physical form - and start to be a sentient beings. After that, they are unaware of the place where they are and... What is everything. Only thing they remember and know from start is the image in their heads showing S3 Cat1 blinking on some kind of console...

Place where the first secati was imprisoned was a big research facility/laboratory with multiple sectors. Cell where they were kept was located in the sector 3 and secati was classified as category 1 "object". Other than blank white walls, sharp lights and masked humanoids, this secati always had image of S3 (sector 3) Cat1 (category 1) in their head, as it was written on the transparent wall of their cell. Before their eyes all the time.

Secati are anomalies appearing on every world possible, being the side effect of magic abnormalities that created them. Energies flowing in universes are simply creating them and "newborn" secati are appearing everywhere. After that, they are unaware of the place where they are and... What is everything. They only know they are secati. Or... S3Cat1 more specifically.

Pronunciation: "Sec-ah-ti"

Secati is already plural:

One Secati, two Secati, eleven Secati and so on.

There is no "Secatis" form!
