All my characters in the past have been full human, recently had a half ausar which then went full and that was pretty cool. But yeah normally stick to humans, being like the baseline in such a weird and varied world just seems cool to me.
If you have the newest backer version you will have to fly around a bit and eventually encounter a quest taking you to Uveto, if you have the public build you will have to wait for the newest version to be released next month.
But the back story for the character would be that of your current Steele, like maybe have different resolutions to the same problem but they would of taken the same path.
