If you think your timing chain is slapping - check your tensioner first, if that's not it, it's time for a teardown, the reason I say "ex" is because whatever it was, it's now ground to a fine powder. Check your stator side - you might find some larger pieces there since it's magnetic as well.
It could be that a bearing let go, and the carrier got chewed up in your gears, I'm pretty sure once you open it up, you'll find some larger pieces in the bottom, as well as one badly damaged component.
Replace ALL your bearings if something metal went through.
Likely, your top end will be alright (unless it came from the top end) because the oil filter would have caught any bits before pumping oil up top.

Did you pass a magnet over the "sand"?
The magnet on the plug I have (Moose) isn't very strong and I would expect that larger chunks would not be held by this magnet. If the "sand" is not ferrous and it doesn't look like metal then maybe you have something else going on.
I see a slight amount of a black grease-like gunk stuck to my plug and expect that to be normal.

I'd be taking off the covers at the very least to see if any debris is behind them that's not supposed to be there..
Are you missing any plugs where the sand could have entered?

This usually manifests itself in a very fine grey sludge you describe on the sump plug and small amounts are normal as the clutch wears.
Knocking could be from anywhere, but I would start with the clutch.
