I don't think our friend is from the "hovery sphere thing" or is even very sure of what it is because he refers to the sphere as "something" and "it". I also wouldn't say he's human because he calls us "you". Maybe he's an outsider? Massive games usually have three different factions (well, at least Planetside 2 does), so maybe there's the Humans, the Sphere Dwellers and the Others, but if Lupi's one of the Others, why would he care about us, then?
