Does the dead body of a Shard pull at time and space, thus causing time to pass slower in that place of the cosmere, almost like a black hole?

It could go either way in the Cosmere, depending. But the answer is yes. A large amount, like a deific amount of Investiture will... any amount of Investiture will cause a bit of time dilation, but the amount you're getting from even a Shardpool is not enough to be noticeable. I mean, it is, you can notice it even on our planet if you take a jet that goes fast enough, so it is noticeable but not relevantly noticeable. We're talking about a slippage of a day or so in a year even off of a Shardpool (don't canonize me on that one, I don't have the actual numbers). But that's what we're talking about. There are are chunks of Investiture of deific nature that can cause amounts of time dilation that would be virtually impossible in our universe, without you becoming one with a black hole. There's a story I want to tell, and I don't know if I'll ever get around to telling it, about an entire society that rises and falls in several seconds of time dilation to everyone else. I want to be able to tell stories like that, and you couldn't do that in our universe, but that's part of the reason we have the Cosmere!
