By choice? I know clans, as a concept, can be... territorial.

[ that sounds diplomatic enough. annabeth has certainly run into her fair share of exclusive, closed off clans in her questing ventures, and the way merrin speaks of her own and her planet gives her that impression. it's not like she was allowed to leave camp half-blood for several years herself. ]

I never left Earth till I got here. But it's not really easy for most people back home. [ she pauses. ] I think in any kind of universe, there's always going to feel like an endless list of things to see. I'm not sure I'll even get to see everything just on my planet.

[ she looks briefly out at this strange sea and thinks of the atlantic. maybe the pacific too, but she has her preferences. she thinks of percy somewhere out there swimming, and it almost feels like if she turned around, the cabins would be within walking distance. ] I like to think so, though I'm definitely biased. I'm glad the storms are gone. Makes coming here easier.

[ never mind all the supernatural weirdness. she is mostly just ignoring that part. ]
