The list of anomaly types, from easiest to hardest:
* (Faction) Burrow / Drone Collection (easiest)
* (Faction) Hideaway / Drone Cluster
* (Faction) Refuge / Drone Gathering
* (Faction) Den / Drone Gathering
* (Faction) Yard / Drone Surveillance
* (Faction) Rally Point / Drone Menagerie
* (Faction) Port / Drone Herd
* (Faction) Hub / Drone Squad
* (Faction) Haven / Drone Portal
* (Faction) Sanctum / Drone Horde (hardest)
A particular anomaly (except Havens and Sanctums) may be further sub-divided into 3 difficulty indices:
* (Faction) Hidden (type) (easiest)
* (Faction) Forsaken (type)
* (Faction) Forlorn (type) (hardest)
In short, a Guristas Hidden Port is an easy “Port" while a Guristas Forlorn Hub is the hardest Hub anomaly you can get.
