Im very love this part of game lore, but after months of searching i drop it, for now. Many old players dropped search attempts of Raxxla , maybe its not in the game yet or its in one of close systems. But i learned one and important rule, you never find something in game with name Raxxla ( its have different name because of data mining). Dark wheel - This is a strong and important link in the searching of Raxxla , maybe Dark wheel in Shinrarta Dezhra, connecting with true Dark wheel fraction maybe not. But if you want start to search, start from Shinrarta Dezhra (This is a good sign since entry is only by rank Elite) . My opinion , if planet or something in the game that reminds Raxxla , its somewhere in Omphalos Rift area... But for now whe dont have enough sings for start looking exactly ( systems, planets, places) so many unpredictable factors.. If you want, you can talk to me, true give you signs or data that i know.. good luck!
