"I've lived among groundlings before," Stone shrugs amiably. "That's what we call people who live on the ground, rather than in the sea or the sky, where I come from," he adds. "Groundlings, sealings, and skylings. But I'm used to being around a bunch of species that aren't my own. The only real weird thing is that there's so many of only one species, the humans. The rest of us are a very tiny group."
