Sis is a god.

It takes the form of a very fat, intelligent swan.

Sis created dark energy three thousand years ago.

If you believe in Sis, it will be very happy.

If you do not believe in Sis, it will hide angry queen hornets in your dwelling place.

Sis' most sacred site is Troqueer in Scotland.
