I preserved the organ in Spacia. I made sure to separate the testicles; I didn't want to accidentally impregnate everyone with hobgoblin children after all. I did end up harvesting the balls though. They were used for medicinal purposes in the cities and could easily fetch me a couple of pent coins. As for the carcass- Snack for the road.
I had money, I had a lot of money now. But that didn't necessarily mean I could just forget about the stuff I had right before my very eyes.
Anyway, now it was a race against time. Things didn't spoil in Spacia. But unless I used a grafting slime on this thing within two hours, it would go bad, or so I'd read.
