I'm planning on a game that has padawans trained by a Jedi that survived order 66 travel to Tython. With their Jedi Master killed, the group has been on their own and I have an adventure idea that will take them to Tython. I've read where the hyperspace lanes collapsed and Tython's surface was severely devastated but I haven't seen much to describe the system and planet during the time of Return of the Jedi, just after Palp's death.
I've read Dawn of the Jedi and am familiar with some of the other planets in the system, are they still inhabited? I am going with the idea that the nine temples are still there and the vergences as mentioned in Nexus of Power are strong. I am guessing that Force Storms have greatly effected the area but the temples are somewhat protected even if they are in less than pristine condition.
I guess I'm mainly looking for any information on the system post-clone wars. I've read the wikia article about the oversectors so I know it will be a challenge getting there but in my game there is quite a bit of confusion and activity in the Core as it is just after Coruscant hears of Palpatine's death so there will be a better chance of them getting through.
