#major apologies if I butchered anything with this. I'm not very well versed in this. just wanted to think of how dr who could connect it

I think Mrs. Flood may be an Osirian. Specifically, Isis / Alozza

If they focus on the Osirian/Egyptian Mythology side of Sutekh, it would make sense: Isis is a goddess that has been associated with a million things. Importantly for this, she is connected to the sky, to rain, and to fate. She was also the sister-wife of Osiris, who himself is associated with cycles of nature. Including, the annual flooding of the Nile.

From there, the name 'Mrs. Flood' tracks! She is both the flood of rain and the wife of its endless cycle. She's also a widow, so of course she would have a married title yet no spouse.

It would make sense to include her specifically, as she is important to the Osiris Myth that Sutekh's history is based on. In it she collects pieces of Osiris that Sutekh/Set scatters after murdering him. After finding them, she resurrects Osiris for long enough to have Horus (or an aspect of him at least). Horus then 'defeats' Set. Which parallels the story in Pyramids of Mars.

Being an Osirian would explain her creepily ominous warning to Cherry. As while she would not be with Sutekh, she would still be a higher being with alien priorities. Her being on earth would also somewhat fit with the dweu. Where Isis waited on earth for Sutekh's awakening. Though not 1-1.

It could also connect back to Ruby, as Isis' has strong connections to motherhood. If Ruby was say, secretly an Osirian, there are options. Especially considering her name's reference to both the Sun and the colour red, like girl is nearly a verbal description of the Eye of Ra. She could be the daughter of Isis herself, maybe a younger aspect of Horus (God of Light but also a god of the Sunday), hidden away as a human. Though that would be a very literal take. Honestly, when it comes to Ruby I'm not sold on anything specific.

Lastly, If they go this direction, I'm guessing the "vital object on a distant planet with no name" that rtd teased, will be related to the Osirians. Since they've already used the Eye of Horus, perhaps the Eye of Ra? It is has been depicted in relation to Isis. It's also often personified as a Goddess so, maybe Ruby herself? A living trap/weapon, idk). Whatever it is though, Mrs. Flood would be instrumental in defeating Sutekh. We'll see.

(Also: disclaimer and apology in advance to both people who actually know about the religions I'm mentioning, and to EU/Faction Paradox fans. For anything I may have got wrong 🙏)
