The Nova Migolatus System brought little to the Hafner System. Colonized and terraformed rather late, the first planet from the star had only been settled by Hafner because it made economic sense. A whole host of AIs calculated that adding an extra farming planet was cheaper than importing more food elsewhere in the long term.
Some time after Nova Migolatus I shaped into a planet fit for human habitation, Hafner latched on an additional purpose. One continent would remain unsettled. Instead, Hafner would import a variety of dangerous genetically modified alien creatures to run a preserve of some sorts. The propagation and mutation of these creatures would be strictly regulated to provide a sufficient and plentiful challenge to mechs.
