Valley of Laponis
The Valley of Laponis is a valley on Macragge. Little more than a cleft in the mountain when Roboute Guilliman arrived on the planet. Within a decade of his arrival it would be thousands of kilometers-long valley which housed the Fortress of Hera, the fortress-monastery of the Ultramarines.[1]
