Indie forces - multiple pretender chassis

[Taqwus]

At the beginning of the game there are a number of specific independent armies that can be placed, such as the one you've seen, one led by a pair (at least) of Cyclops, one led by a paladin, and so forth. In addition to unit choices, these Groups may have predefined magic sites or equipment.

Sounds about right. I've seen some other armies, just not with multiple Pretender type chassis present. They all had equipment and gems in their inventory too!
