How did the Shards get to their planets?

How did the shards get to the planets they are on and why?

Were any planets created by a shard?

They're capable of movement between planets, Odium seems to do it the most, we're not entirely sure on the mechanism, whether they just fly through space or use Shadesmar somehow.

All of the Shardworlds so far were created before the Shattering of Adonalsium I believe.

Didn't Ruin and Preservation create Scadrial? Thus the deal that Ruin can destroy it.

They created life on Scadrial, yes. Not sure about Scadrial itself.

WoR implies that Adonalsium created Roshar, at least:

Is not the destruction we have wrought enough? The worlds you now tread bear the touch and design of Adonalsium. Our interference so far has brought nothing but pain.

 

I find it likely it(?) also created the rest of the planets.

 

I'm also very unclear on whether Ruin and Preservation created the planet, as Sazed says that a rock is made of half Preservation and half Ruin, but atium made of pure Ruin. This seems to say that they created the planet, but we've had several WoBs talking about how when a Shard Invests a planet, they infuse everything, so perhaps not.

 

We don't know a lot, in summary! This is further exacerbated by the fact that the Cosmere's underlying mechanics were still being added to/changed as late as Elantris.

So Adonalsium probably created all of the planets.

I wonder if the shard holders had similar powers to Hoid before taking their shard and combined to help shatter Adonalsium. Or they may have been opportunists who took advantage at the time to take their shard.

It sounds to me so far that they thought they could do a better job so helped shatter Adonalsium, took up a shard then fled to whatever planet they wanted to play with.
