I thought this character was really neat during the "Return of the Archmages" series and I wonder what ever happened to him during the Spellplague. Does he still exist or is he gone?
“Fantasy is escapist, and that is its glory. If a soldier is imprisioned by the enemy, don't we consider it his duty to escape?. . .If we value the freedom of mind and soul, if we're partisans of liberty, then it's our plain duty to escape, and to take as many people with us as we can!” #8213; J.R.R. Tolkien
I don't recall anything be written about him after RotA. I presume he's still alive as he was effectively immortal but...was the magic linking him to this world severed (I don't recall)? If so, he may have finally perished.
I have a dream that one day, all game worlds will exist as one.
Jhingleshod swore to kill his master Wulgreth and that he would not rest until the lich was dead and gone. Since Wulgreth chose the Heart of Karsus for his phylactery and the Heart itself was taken by Shar, its a good guess that Jhingleshod is still around, waiting for the day his former master can truly die.
