The ML seems to be down so I'm sending this directly to you as well. Got 
anything from the ML in the last 18 hours?

It was her usual home, in Valhalla, where her family dwelt.

And is Keiichi still with her after all these years?

        "It's a small moon that is divided by a magnetic field.  The

left side is anti-matter.  When I push a button on this," she held up
a remote control, "the field vanishes and the two halves slam
together and explode." <<

It's a common misconception that this is how a anti-matter bomb should 
work. In reality, it's a very crude method of making an anti-matter bomb. 
You see, only the matter and anti-matter on the contact surfaces- where 
they actually meet- on both halves would convert into energy. That's less 
than 1% on a bomb of this size. The rest of the material would be merely 
blown apart by the explosion. Rather inefficient don't you think?
The correct way of doing this would be to suspend lots of tiny packets of 
matter and anti-matter next to each other in a force-field. drop the field 
and almost all, more than 90%, of the material would be converted to 
energy. I'm sure Washuu would have figured this out too. It's well within 
her powers. And the bomb could be a lot smaller too.

Anti-neutronium isn't any different from neutronium and it won't blow up 

in contact with >other stuff.

I'm not too sure about this, I once read a story about using an 
anti-nutronium bomb to turn the Earth into another asteriod belt.
