Future expansions.

In the fantasy settings, the Wood Elves have a higher priority than the Dark Elves.

And they also have a higher priority than the Nagas. But Ubisoft has its own priorities.

Judging by all the indicators, it is most likely that the Faceless Ones will be the champions for the Dark Elves.

Based on what indicators? Ubisoft said that there will be no dragons in the game for the factions, only bosses. But he didn't say anything about expansions, it should be noted. So, Champions of Darkness could easily be included, especially since it's such a classic classic that they wouldn't just abandon.

But the contract forbids them from fighting.

And who said that they will release expansions in chronological order? Maybe they will want to start from the end?

These are just dragon icons, not faction icons.

In this case, the dragon icons coincide with the faction icons that they patronize. It's not for nothing that forever alone Silat doesn't have an icon in the picture.
