No, no, let's not evoke Tolkien here. That's going to be pretty meaningless at this point. If an editor says that your work reminds him of Lord of the Rings, fine. Otherwise, it's in your best interests not to bring the most comparey work of fantasy fiction up.
Here's a version that is likely to have some details wrong, but may work a little smoother:
I'm not really adding much there because I don't know anything.

I don't know if the lich wants revenge, but if that's why he's going after Andora, that can be worked in there, as you see. If he's going after Andora because Andora has magical bonsai trees he wants or whatever, you probably want to just try to get a mention of that in there. If we have a general sense of
why people are doing things, we tend to be more interested in what they are doing.
The problem with the second paragraph is that not only don't we know why people are doing things, we don't know who they are or what they are actually doing. So either I'd say you don't mention them at all and go with something like "As Hannibal stalls for time and war breaks out across Andora, (because?) forces shift and coalesce around him. Aid or destruction is on its way," etc., and just keep it all on Hannibal, or you need to briefly name each of the other key people of that group, briefly what their central situation is and then how that relates to Hannibal and those priests being or not being resurrected. If those three or four characters have really interesting situations, that helps sell interest in the book. And then of course, there's the demon, who might be handy to mention.
I think if you want to pick a Salvatore novel, that The Demon Awakens, the first in his DemonWars series, is probably a better fit than The Crystal Shard, which is essentially a military battle fantasy in the D&D universe. Other than that a demon manipulates events to create war, I'm not seeing a lot of crossover between your book and the latter one. And then you want something that is like Salvatore so the two references make sense. You don't seem to be writing a horror novel and you don't seem to be writing a mystery, so the references to Stephen King are not going to make a lot of sense to them. I'd suggest someone else like Robin Hobb, Raymond Feist or Gene Wolfe.
