Well, a couple of characters come to mind.

J'nkai - alien mechanic, blue-skinned humanoid with multiple limbs, got stranded on a world with a long abandoned mine and no way to get outsys until they got rescued a decade later.

His silent partner (they're mute) calls herself Seven. She's a human and very good with guns, blades, even her hands. J'nkai believes she's a Wilder - a sect of humans who claim they were the first to leave the long lost mythical Earth. He actually found her in an active frozen berth in the wreckage of one of the orbiting ships.
