I say Yme-loc because they have a very small background but what they have is so intresting i would love to know more
While I really like Alaitoc, then I think it's most likely going to be Ulthwe because of the area in which Eternal Crusade is going to take place (As it's really close to their craftworld).
Why do you think the Eldar would have only one Craftworld while Spess Mahreens have 4-5 chapters? Ulthwe is like Eldar Ultramahreens, it's posterboy Craftworld for no special reason) Thanks for Eldrad, Ulthwe, you are dismissed)
Apologies, I had forgotten the part of there being several chapters and such. In that case, I think the most likely to be Ulthwe (because they're always there ), Alaitoc, Saim-hann, and I'd like to see Mymeara because I like their colour-scheme. Otherwise Yme-Loc as Khan suggested since they have very little information on them as it is, and their craftworld should be in the area around the Eye of Terror.
There still is a possibility of Iyanden, it's a pretty prominent Craftworld, but its emphasis is on automatons, and they are unlikely to be playable in EC. So Iyanden may well get omitted.
Yeah, that was why I didn't include them in my suggestions. With their force mainly being made up of Wraithguards/Blades/Lords/Knight etc. I just don't think they'll be put in the game because their most iconic units would be unavailable for players to play anyway. Makes more sense to try and bring in something new and fresh to flush out some lore.
I have a idea on three of them but no idea on who the other two will be. I'll play Biel-tan at first because Macha is my waifu.
I voted Biel-Tan because I really like the concept behind the Swordwind. But, real talk, I'd pick Altansar and it's potentially creepy lore over anything else.
Would love to see some under-dog craftworlds that havent been showed that much like Kaelor, just to freshen things up for a bit. Story too like reemergence after milenia with more powerful psykers
