N.T.S. Stellar Explorer

The first massive starship worldship launched in Tranal Nomads history. The Stellar Explorer is almost 100 km long.
N.T.S. Stellar Explorer is a huge worldship and primarily designed to synthesize hydrogen fuel from gas giants in order to fuse it and produce power for the planned (at the time) fleet. The Stellar Explorer would also have a lot of ship to ship weapons and could likely hold out against a powerful enemy force even on its own. N.T.S. Dawn is still more powerful.
The Stellar Explorer has a large number of hydrogen collection shuttles, and also a very large cable on its exterior that can expand down to a gas giant that it is in low orbit of and harvest it.
The Stellar Explorer has developed a different culture compared to any that are seen on the Dawn. This is due to the difficulty of moving between the 2 ships compared to moving within one ship. N.T.S. Stellar Explorer has a population of almost 1 billion. It is also notable for having several conflicts happen inside it. These turned out similar to those on N.T.S. Dawn, and eventually led tot he unification of the starship.
Rather than cancelling gravity through archaeotech, the N.T.S. Stellar Explorer does it through Graviton Wave Refraction, a technology discovered due to the archaeotech artifact.
