And that isn't important? All you know is that he created for that reason, not who created him or why he was created. It also properly foreshadows him, without Leviathan all you know about the Catalyst as that it's a thing you need for the Crucible. Not really what it is or what it does, just that it exists. You can say "But oh, he was mentioned!" that's not proper foreshadowing. Knowing that something exists and is a thing isn't proper foreshadowing.
