The Forces of Mandalore

Concordia is the moon of Mandalore. It's not mentioned in the show, but the descriptive audio track does reveal when the fleet arrives in the Mandalore orbit. I'm sure it's in the chat with Concord Dawn. Is Concord Dawn a place or is that the other moon? That's what I'm guessing. And then the other question that I posed earlier is which warlord do we want to put our money on prevails and is sort of the incubator the first order (Darth Maul)
