so I have finished MoI and I have to say this was the most satisfying reading experience so far. The first book where I think there were more answers than new riddles.
Things I loved:
1) the prologue(s). I read them very carefully and learned a lot. For instance, I think we saw how the imperial warren was created (Kallor's destroyed continent). Also, when Toc woke up in Morn, I kind of was able to guess parts of the plot. We got some information from the Imass in DG, one of them closing a rent. Also it became pretty clear who Nightchill was.
2) Stuff from GotM was answered. Why Tayschrenn killed Nightchill (she apparently wanted Dragnipur). Still doesn't really explain A'Karonys and Hairlock's demise at least as far as I can tell.
3) Tattersail/Silverfox. I now kind of understand what happened in the Bellurdan/Tattersail/Nightchill incident. Still, in GotM, Tool made the enormous magic field which created Silverfox, so why can't he do magic in MoI? Also, it was alluded that Kruppe and K'rul had a hand in that. I reread the scene from GotM and two of Kruppe's dreams, but I can't find any hint how Kruppe or Krul had a hand in Tattersail's rebirth. So maybe I don't understand it after all?
4) The Trygalle Trade Guild. It felt very tacked on and unnecessary in DG. Good to see more about them (although they're insane).
5) Fener's downfall. I think I now have a good understanding what happened. Now, it says that Fener now walks the earth. Did we actually see him in DG or MoI? If so, I missed it.

6) Baudin get's to be Hood's knight. Woot
7) Toc comes back. Woot (although he then dies and resurrects as Anaster?)
8) Tool gets laid. Must feel good after a dry spell of what? some hundreds of thousand years?
9) We see inside Moon's spawn.
10) Quick Ben outsmarts everybody.
11) You gotta love the Mott irregulars.
12) Many more stuff I could mention here.
Now, with all the goodness, here's some questions:
1) It seems Kallor's history is pretty much known to most (important) people. Why would you have this jerk as an ally in the first place? Moreover, he was cursed to never become an ascendent. Except, now, he is. Why did he get a free pass when Nightchill, K'rul and Draconus didn't?
2) The 'master of the deck' power upgrade: 'draw card'. I liked the 'bless' upgrade, in particular since Ganoes kind of stumbled upon it. The 'draw a card then punch it', seems weird. Why not use it on the Seer, or the crippled god?
3) The whole body-switch thing. I can accept someone 'ascend' (before or after dying) and keep his or her body. I can accept Duiker being resurrected as Duiker somehow. I can also accept rebirth as in Coltaine (the Wickans in general) and Tattersail. What is new, and it grates me a bit is the idea of a body switch. I felt wrong. Also, how did Tool get a body? Or should I ask whose body?
4) The whole Togg/Fanderay/Mhybe storyline. I get that K'rul can make warrens. I also get that dreaming women apparently can dream up whole worlds. So far so good. But the whole Togg/Fanderay thing came a little bit out of the left field for my taste. Fanderay was somewhat connected to Baaljagg? Where did Envy find her, then? And how did Toc get connected to Togg (well beside the name coincidence). What was Silverfox's precise game (well she wanted to create the world for the Mhybe, but I guess I didn't get the whole wolf thing which was going on between Toc, the Mhybe and Silverfox).
5) Seguleh. Ok, I get it, they're awesome. But THAT awesome? It's very over the top.
6) The whole 'race to Coral' thing. Ok, with Capustan, the Pannion's seemed like a real thread (big enough to make the Malazans and Rake_Brood work together). Then they got their behinds whacked by the Barghast. Once Capustan was liberated and more intelligence came in, it seemed to me the Pannions weren't that much of a threat any more. I think it was clear to everybody that the whole empire was emptied of people. Everyone was holed up in Coral. Why not just let them wait there until they eat each other? What was the rush? Burn still has years left (if not decades). The poisoning of the warrens didn't seem that much of a point in the latter part of the series (Mallet healing Paran after the condor incident). So, what gives? Let them rot in Coral.
7) Itkovian. Couldn't he wait a bit before his big stunt? The Imass could have ripped the K'ell hunters apart first. As it played out, Gruntle's company and the grey swords had to take on that job (and they lost many, many people) before the Ay arrived. Yeah, way to go Itkovian. Great timing. The whole thing got worse IMHO, when the Imass decided not to be released by Silverfox after all, but to look into this other war to the south. Against a human empire (I guess we'll learn more about it later). If they're ready for another war, they could've waited a bit in Coral, too, IMHO.
8) Whiskeyjack. I didn't get it. So he's a great guy. What didn't work for me is why he made such an impression on everybody. Rake, Korlat, Brood etc. Actually, I didn't like the Bridgeburners very much in GotM. Putting mines throughout a whole city? Not nice. I was rooting for the Darus all the way. In DG, I was ambivalent to the whole uprising at first. Only toward the end, I came down on the side of Coltaine. All in all, I got never that much attached to the Malazans. Whiskeyjack and Dujek are obviously very capable commanders, but the precise quality which impressed for instance Rake so much, I must have missed. It was tragic when he died, but the emotional impact was much less than Coltaines and Duikers deads in DG.
9) The one big mystery is now the crippled god. What's his game, how can Burn survive (I guess the Jaghut ice pack is just temporary relief) and what was the deal with the poisoned warrens. I guess it was the crippled god's work, not the Jaghuts?) Anyway, is it better now or not? Quick Ben found his solution, but what about the other mages?
Anyway, I've started book 4. The prologue didn't tell me anything and after the first 100 or so pages, it feels so different from the first three books. Does it connect at some point? I guess that's a discussion for the next forum. Thanks for reading my ramblings and any kind of response is appreciated.
