[X] Kill it. The last person who entered your shoals died, and you will help this one along. Maybe you'll garner more energy from this one's death as well?
Upon reflection, I think I'll go with this instead. While I am definitely more curious about what'll happen with letting it come closer, I think killing it will prove more condituitive for the direction I want the Endless Water to go in.
Not that it'll likely matter because Let it closer is genuinely shiny and even I have a tough time not picking it.
Also, there's a chance that letting this person in means our eventual Avatar will be based on their body, as they'll be the Human/Being we know the closest.
the killing should count toward opening up the Death traits.
I am not too sure about this, actually. While yes, we'd get associated with killing people, it's not like "go swimming during the arctic winter" is a particularly special cause of death. It'd happen even if there was no action taken, and no one else would know we were responsible.
On the other hand, I think this person is currently doing one of two things: Either they're insane with anger and wish to wrestle the ocean, or they're so disraught with grief they're actively seeking the same death as their loved one. And if it's the latter case, I think accepting them will tie us a lot closer to death the "calm embrace of the sea" type of underworld/spirit.
Watch them nearly kill us and ascend as a competing spirit as it 'protects' the people from this malicious entity that killed his/her lover.
Could also be a grown up child; a beloved sibling; a best friend or a "best friend".
Human relationships are so much more confusing than the fishies'...
and she'll tell us to go fuck ourselves
Incidentally, also something Harzivan did.
