Well, we can try to make one now that all the scenarios are done. We know that:
1. The Calabim, Elohim, Malakim, and Khazad are probably close (Into the Desert)
2. The Doviello are near the Illian (Age of Ice and Scenarios)
3. The Amurite and Elohim are close to the Infernals (Valledia and Einion's pedia entries)
4. The Bannor capitol is close to the Grigori, but separated by a sea (Blood of an Angel)
5. The Svartalfar and Ljosalfar are close to eachother (Splintered Court)
6. The Sheaim and Kuriotates are close to eachother (The Cult)
7. The Bannor and Clan are probably close due to the Orcs settling the Bannor exited Hell
8. The Khazad are close to the Hippus, Lanun, and Clan (Against the Wall)
9. The Bannor and Lanun are close (Fall of Cuantine)
10. I imagine the Luchuirp are close to the Illians because they attacked before the AOI
11. The Khazad and Luchuirp are probably close due to both being Dwarves
12. The Balseraphs are probably close to the Sheaim (Perpentach's pedia entry)
13. The Infernals probably spawned near the Sheaim, meaning so are the Kuriotates
14. The Hippus are most likely near the Lanun cities on land
And if you wanna get into the Fall Further civs
15. The Kahdi would be close to the Amurites (Kahd's pedia)
16. The Scions of Patra are probably close to the Bannor (Scions of Patra pedia entry)
17. The Dural are likely close to the Kuriotates and Bannor (Karrlson pedia)
18. The Mazatl and Cualli are likely close to the Clan because of their jungle preference
19. The Mazatl are likely close to the Sheaim (Hianthrogh's pedia entry)
20. The Jotnar are likely near the Dwarves because they tend to start in mountains
Just saying.
