Is there any backstory for the talon available? Is there a 5th long lost talon clan? If so, what were they called? thanks in advance!
Not yet. For the vanilla (default random survival) game there is some lore on that, though (which has not been revealed yet). Spoiler The 'tribal' Talon you meet near the Zirax territory/on the starter planets are not the only ones in Andromeda. If you played through the story missions, you already met one of the "others" that managed to escape the Zirax hunting them at the end of the War of Silence; More to be revealed in the remaining 4 story missions
