Stefin-Dae should have died on Slabour, like all good Diggers do. After a few years of grubbing in the earth for Creeliu m--the most precious mineral known to man--Stefin's lungs should have been so full of red dust that there was no room left for air. But Stefin got lucky, or maybe it was just his destiny. He escaped from Slabour, stumbled on the key to the universe, the secret of synchronicity.& became the most dangerous man in the inhabited galaxies!
