Who and what ARE Krell anyway?

The big machine that got us into trouble on Altair.

We are few, we are peaceful,
we are proud.
We are highly evolved.

Unbeknownst to everyone (including Wikipedia),
a few of us miraculously survived
the cataclysm on Altair,
and escaped to Earth.

We changed (physically, at least).
We adapted,
or are trying to.

But living here on Earth can
be a bitch sometimes.

Still, these primitive humans need our help.
Badly.

It would be tragic for them to make
the same mistake we made on Altair.

Ofcourse, right now, it looks as if the people of
Earth will be lucky to last another 20 years,
much less another half-million, when they too
may face the crisis of
"Civilization without instrumentality"
that proved so devastating for
our own civilization
over 100 centuries ago.

But Krell civilization
rocked for 500,000 years,
before our, uh, miscalculation.
We thought we had it made.
Oops.

That's still a heck of a lot longer than Human civilization has had it together. And they look like they could screw-the-pooch much earlier than we did on Altair.

Perhaps this Blog can turn things around?

We can only do our best...and hope.
