Fast forward to my next login, at the very southern tip of Terrors spawn. I was planning on hearthing, but I saw the corpse of Desperiona, which for some reason made me feel like checking just once before I did, when low and behold "Shiiing" says npcscan! So, heart pumping, I tag Terror, without realizing my other pet was still out, at which point, during the dismissal, Terror proceeds to nearly kill me, resist my FD, causing me to shadowmeld. I eat. I pray no one comes and takes him, since he walked out of my view. Get full hp, run to where he went. Still there. OK. Deterrence. Tame beast.
So I finally got Terror after a brief hiatus of non camping.

EDIT : As I was posting this, Sambas spawned! So now I have a nice lion as well, whom I named Kimu, which is japanese for "gold"
3 down, Terror, Jade, and Sambas. 3 to go!
