I also hope Morrolan stayed in touch with him because that would be a truly delightful friendship.)

I feel like he absolutely must have, because first, Vlad asked him to look out for Noish-Pa when he left, and that seems like the sort of responsibility Morrolan would take seriously, and second, I can't see Morrolan passing up a chance to get to know Noish-Pa better, both as a master witch and as Vlad's grandfather. I hope we get canon confirmation of Morrolan dropping by Lake Szurke to visit him occasionally, but even if not, it's an indelible part of my headcanon for the series :)
