Honoghr
this once-lush paradise of a planet is the homeworld of the Noghri, and was virtually unknown until it was nearly devastated following a starship battle in its orbit. The Emperor, upon discovering the Noghri, conceived of a plot to enslave Noghri, with the help of Darth Vader. The huge space battle took place above the planet, and one of the ships was destroyed. It plummeted to the planet's surface, setting off earthquakes and releasing toxic chemicals into the atmosphere. When Vader arrived to offer aid, the Noghri readily accepted, and made Vader their Lord and Savior. However, Palpatine had arranged that the decon droids sent to the planet would continue to poison it by planting modified kholm grass. This modified grass would choke out all other vegetation, while making it appear that the planet could still support life. When Princess Leia and Chewbacca discovered the plot following the downfall of the Empire, they quickly worked with the Noghri to remedy the situation. After the deception of Darth Vader and the Emperor was made apparent to the Noghri, they quickly joined the New Republic. However, all efforts to restore the planet's broken ecosystem turned out to be futile, as the once-green world was incapable of recovering. The Noghri eventually relocated to the planet Wayland, leaving Honoghr for dead. It is the fourth planet in the Honoghr system and has three natural satellites. The system is located near Kessel and Fwillsving. Honoghr has a rotation of 23 hours, and its orbit lasts about 352 local days.
Personally, Dolash has a point in that Gue's logistics make no sense if you are dealing with a relatively small population (thousands? I don't think so.. perhaps a few clans) living in a limited habitable area.
Still, Gue has a point that just because that is so does not mean ALL Noghri would have left. If Dolash used force in their removal, in my opinion ALL Noghri would reject the Coalition and use their abilities to strike at them. It would be a violation of their culture.
I would say 10-20% given their small numbers would remain.
However, anything more on the subject will have to be determined by the quality of the roleplay in question (ie: Noghri remnant reaction to invasion and oath-breaking if that be the way BDE goes).
