As for other successful resurrections, I'm told that Thalmarkin was in significant part a refounding of Ar Agyr. Surely there's been a few in Dwilight?
When AA fell it's nobles split into two factions, one joining Old Grehk and one Melhed. AA's lands were then divided, Old Grehk took Vore, Jedinchel and Vatrona and Melhed worked their way up to Lin Helon. OG's AA exiles then joined with Riombaran and OG nobles to found Thalmarkin in Nuzanki and Sandefur and Melhed's AA exiles founded Valentia in Unger.
Valentia interestingly was the first and only realm ever to seize to exist because of the Duke of it's single duchy (which was also their king) changed allegiance to Melhed when they saw the Old Grehkian army nearing.
They seceded at the start of the first invasion and were then crushed by daimons or undead or whatever roamed those lands back then. So you can add Valentia to the list of refounded realms as well, even if one is more successful than the other.
