Selenia was the first character I've "seen" died and come back. That was memorable to me. Created quite the interesting situation.
I'm pretty sure Seoras (vita) also died and later lived again, although Selenia's healing scroll dead thingy was quite remarkable yeah.
And unfortunately my plans never quite made it far enough to actually reach this list for now. I'm mostly sad that I forgot some of the names I played with in the old days though. Still Kanuni Kalkandelen should always be in such a list for me, from back on the old War Islands and later Fontan.
