Algine - X766977 4
Algine/Regina (0803.X7669774). This world is interdicted. A naval task force
(perhaps a Kinunir class battlecruiser and several Gazelle class close escorts) will not
allow landing on Algine and are uncommunicative as to the reason for the interdiction.
They will allow refuelling by skimming the local gas giant. (A3 Twilight's Peak)
It's a naval interdiction.
"Algine (Spinward Marches 2308) is an interdicted world, its entire star system under IISS jurisdiction." [GT: First In, p. 141]
It's a Scout interdiction. 
Settled twice, once some undetermined time before -1511 (my suggestion is around -2200), the second time around -1000.What else do we know about Algine from canon?
Most comprehensive writeup of Algine is the one in FI. Unfortunately, Jon didn't know about the reference to a population prior to -1000, nor the retcon of the star's type, so there are some problems with it. There are still a lot of good stuff about the local population to be found, though.
