The Thoralf-Sigurd-Vig shipping company manufactures all kinds of civil and naval vessels. After Visari's rise to power, the company rapidly expanded their array of products. In preparation of the Second Extrasolar War, Thoralf-Sigurd-Vig produced railways, trains and cargoships in order to boost the Helghan industry. Later on, they use their knowledge to build a large space fleet.
Also importantly, but rarely mentioned, is their large food production department.
