Secrets of atlas or merceneries of trathus

I'm sorry i'm a bit confused.

I downloaded the game and i could choose between standard-mercenaries-hc merc.

Is mercenaries the new leage? Or what is the difference between Secrets of Atlas and mercs?

Could someone tell me please?

League = Trarthus (mercenaries)

Choices: League OR Standard

Same as: Settlers of Kalguur, Affliction, etc.


Expansion = Secrets (ONLY the endgame)

Exists as the ENTIRE game, every mode. You will play secrets of the atlas whether you choose standard or trarthus league.

Last expansion was Maven, Eater, Exarch a while ago.
