Why wouldn't Malakaus know about the Azura Star?

1) It may not even be that anymore. I'm pretty sure the items change throughout the eras 

2) There is no reason to assume that he would. Where would he learn about this from, and its properties? I highly doubt that anyone wrote about it. 

I want to make it clear what's been happening here. Within the last few hours you've suggested your character create the gun, and that the whole party should travel to a completely different area in the world, specifically, in order to get the proper metals to do so, despite our reservations. And that the whole crew should travel to a part of the world in search for something completely unrelated to the storyline, of which there may be no historical proof, so that we can have an item, only for the items sake. This all seems rather self-centered to me.

Can't say I'm certain what everyone else would be doing, presumably they'd also be helping getting the star, or finding their own artifacts.

And this is pretty much why this whole thing is a bad idea.
