Techrog is a planet essential to the ecomy of the Terran empire. For 200 years, it has been a centre of industry, research and agriculture. Suddenly, the indigeus population - believed long extinct - comes back to the planet they kw as Alflolol. Earth's laws are strict: They must be allowed back on their ancestral grounds. But when Valerian and Laureline are assigned to facilitate their 'reinsertion', they see the difference between the letter of law and its spirit.
Jean-Claude Mezieres and Pierre Christin created Valerian in 1967 after working in the USA together, one as a cowboy, the other a teacher. While Valerian is Mezieres' only comic series, he's worked as an illustrator in many other areas, including designs and sets for The Fifth Element, and he was awarded the Grand Prix du festival d'Angouleme in 1984. Christin also works in collaboration with other artists such as Tardi and Bilal and writes novels and film scripts.
