One can imagine that fighting a godling or the soul of a god will be more difficult than convincing some angels to help them. This is why they chose to go around looking for the angels of history and the angels of knowledge first.
Fortunately, while the angels of history are smart enough to hide themselves after learning of the many past events of cocky angels being killed, the angels of knowledge don't hide their location.
In fact, anyone with a modicum of knowledge of the world of tenebrum can guess where the angels of knowledge can be found. Legion has a lot of knowledge, so they can also guess with some certainty that angels of knowledge can be found in the organization known as the White Tower.
The organization called the White Tower, or the Tower of Knowledge, are the producers and sellers of arrays. The godclads in this organization belong to the pathway of knowledge.
