The Quartet (Eldritch Creature)

Per'Cees, the mother to Cassie's octopus thing, Benedict's octopus thing, and Balboa's octopus thing.

Regardless of how we see octos and squidos as two different species, wherever Per'Cees comes from, they're from the same ancestors.

As it turns out, Squids are the females and Octopus are the makes, which would explain why all of the McHartees have male octos.

Per'Cees came to earth very long ago after the death of her husband to a solar flare, it wasn't until the dawn of the age of piracy that her children seemed to have ran away, probably seeking to learn and make human friends.

This was concerning since Per'Cees had only seen humans wage wars and hate, surely this meant all humans were all like that.

It wasn't until the 21st century that Per'Cees would have narrowed down her search of her children to one family bloodline, how interesting.

In order to watch them more closely since they're were hidden by an arcane shield, she took control of four children at young ages, and getting them to all meet under various circumstances, though, since her children weren't really in any immediate danger and it gave her some ease, she kind of got sidetracked with how interesting human music was.
