Should've never thrown me into the birdcage

In my crossover AU where all spec-evo planets that have something to do with humanity or terran life in general are imagined as colonies/members of an interstellar FTL terragen empire. Previously, i added:

1. Earth (obviously)

2. Snaiad (alien world with human colony developing its own culture)

3. Darwin IV (alien world humanity explored extensivly).

Now i added three more planets per suggestions and my own searches.

4. Phtanum (one of the lost human colonies on an Alien world, reconnected)

5. Magna Foraminis (a seedworld made by "precursors"*)

6. Serina (a moon seedworld in its ice age which nonetheless serves as the homeworld to three whole sophont species that are members of the empire.)

For this whole thing to work (to explain why Earth is the same while all other seedworlds present are supposed to be millions, hundreds of years away chronologically) was easy – i had to invent "precursors". Dont think about them, they are dead anyways, but atleast they terraformed some planets with terran life for us, so... thank you?

Please feel free to submit some spec evo planets you know. The only condition is that they must not have magic, be homeworld/colonies of an advanced(!) Alien specie, and (optionally but preferebly) have in-lore connections to humanity (colonisation, exploration). And please make sure they have maps avaible.

i wanted to do some crossover thingy and gather as much spec-evo planets as i could in one page and imagine them as parts of one interstellar empire of humans (and some other seedworld sophonts that achieved spacefaring level), and also test my new pencils and pens, but thats unrelated.

So i wanted to ask you guys about what planets and moons in spec-evo you know and can tell me about? Main condition is that the object must have some world map avaible and not be a homeworld of spacefaring ALIEN life. It can be a planet with animalistic alien life, planet with some extremely primitive alien sophonts (like Darwin 4 over here), or (most encouraged) a seedworld.

Especially encouraged if in lore the world had directed interaction with humanity, like colonisation, terraforming, or atleast a flyby of a space probe.

So far i included: –Earth (obviously) –Snaiad (alien planet with human colony that allready began developing its own culture) –Darwin IV (one of the first places humanity found life on and visited directly. In this canon Yma never showed up and humanity never screwed up the Earth.)

Next on the list were Phtanum b and Serina, but i wanted to make a little survey to check whenever there is something more.

(Also ignore timeline inconsistency and etc, just handwave it.)
