History: Oo'Sarr, are a proud and patient people. Ice dwellers. These massive beasts have been hidden under the surface of the Arctic for generations. centries ago the Oo'Sarrians had made a break to the surface with their massive horn like beak. Now seeing that there was more to explore. The people had moved from the depths, to the surface. As the creatures had slowly explored the surface, the Oo'Sarrians had soon learned that they were not alone. Massive structures that were in the deep of the ice. it was slowly learned that these massive structures were ships that have crashed millennia ago. If it were not for the curious of the Elder, they may have never discovered dust that lay deep in the cargo of the ship, giving the furred/scaled people an increase in intelligence and understanding.

     Years have past, and the Oo'Sarr have now become a space dwelling species. Making titanic sized Ice vessels, and with the desire to explore what there could be out in the sea of starts. Ships maybe slow, but their hull clearly makes up for the speed. As the generations have past, the Oo'Sarr are now on the verge of space exploration. 

I like the Endless-based lore of these guys. Sets them up nicely for a faction-based questline. And the icy-themes are fun. I don't remember the traits you list by name from ES1, so you would have to spell those out for me. Anyway, good stuff, and good luck!
