Mars and the Valles Marineris

Valles Marineris is 4000 km (2500 mi) long and reaches depths of up to 7 km (4 mi)! For comparison, the Grand Canyon in Arizona is about 800 km (500 mi) long and 1.6 km (1 mi) deep.

From the depths of the Valles Marineris via the canyons of Baetis Mensa, the mutant pilgrims rediscovered their ancestory. In the shadows they found the entrance to Unterheim and to their amazement that the facility had been waiting silently for their return.
