shoop's luonto suddenly makes me wonder: if your luonto's aquatic, what does it do if you're on dry land and need its help? Does it 'swim' through the air? Crawl over the land as best it can? Can you not leave the seaside if your luonto's a whale shark or an octopus, for fear of distancing yourself from it?
Hmm... as cool as that would be, I don't think that would be the case. I mean, just look at the info page. There are rabbit and snake Luonto's that simply seem to be soaring through the air. They're not land-bound like real animals would be. Besides, the Luonto seem to be a part of you - a part that CAN leave your physical body, but that isn't necessarily doing so. If a fish Luonto had to remain in the water, that would probably mean that their person had to, as well, because otherwise they'd be separated for the better part of the persons life.
On the other hand, I think it would be pretty cool if your physical location determined your Luonto. Like, if you're raised by the seaside or by a lake you might have a bigger chance of attracting a fish Luonto, while animals like rats, pidgeons and sparrows, and domesticated animals might be really common for city folk.
