Just gonna post this here: I am always looking to buy parentless dragons. Not much treasure right now, but we can make a deal where I pay you in installments/hatchlings/art or somesuch.
I'm Arrow over there, finally got things loading properly enough to start. I was stuck between Nature and Earth, but I ended up going with Nature (final decision totally not based on dragon eye color...nope, not at all).
