That all came about because of a really strange coincidence.
I always knew that @SpiritSeer was going to be introduced later.
Then @Sellalellen won–
In the Nepenthe drive last December.
I had plans to have a different character reach out to whoever won that (oddly out-of-world) part of Nepenthe, but then when I looked back on the Fan Club post replies, I saw that, out of all users, Sel had been the one to do a fair amount of research on the Fan Club users, including Spirit, and Spirit and Sel felt like the perfect match.
