The longer version, since I’ve read all those books, is that Mieliki saved the souls of Catti-Brie, Wulfgar, Regis and Bruenor when they died. Drizzt kept going, had a very dark time in his life, and Mieliki brought them back to help him. Apparently there’s some big fight between her and Lolth or something.
Anywho, all Drizzt’s friends were reincarnated into new bodies, but with their full mental facilities (they were fully aware of their own births) and lived for 20 years before meeting at a certain place to save Drizzt, much to his surprise, seeing all his friends who had died so long ago.
As was mentioned before, WotC came to RA Salvatore and said “Everything’s fast forwarding 100 years. Deal with it.” But only one of his characters would live that long, so he had them all die in dramatic fashion, while being kept by Mieliki to be reincarnated later. That way, he could continue and tell the stories he wanted with the characters he wanted, and just had to deal with a little side track of “What has Drizzt been doing all this time.”
All in all, it is one of his better story archs, in my opinion. Watching the four of them grow up, with full memory of their past lives, was rather enjoyable. Regis really was never a great character before that, but the cool thing is Regis had come to this same realization, and therefore decided to make something of himself in his new life. Now he has an enchanted rapier, an enchanted dagger, a hat of disquise, is an accomplished alchemist and has a bag of holding. Catti-brie, who was another one I never really got, also came into her own, studying as a wizard and chosen of Meiliki, becoming a rather powerful wizard (the one class that was severely lacking in Drizzt’s party). Bruenor stayed Bruenor, but it was fun watching him as an 8 year old Dwarf learning to fight with the other 8 year old dwarfs, trying to pretend like he didn’t have 250 years of battle experience behind him. Then he went and revealed himself to all the other dwarfs, convinced them he is who he says he is, and they all went to Gauntlegrym to take it back from the Drow who had made a living there.
Even Wulfgar is more enjoyable, as he’s decided he’s just going to enjoy this new life. He died as an old, old man in his previous life, had a family and kids, and now he’s just having as much fun as possible. Much different from the brooding barbarian of his first life, who had literally gone from hell and back and had to be rehabilitated from both that and the drunkenness that followed.
Normally I don’t like the comic book ‘they aren’t going to stay dead’ trope, but in this case, I understood it, and I approved. It was done well, in my opinion, and helped breathe life into a series that was turning rather stale…
