Wormholes

The Hemelein system has the following wormholes:

1. N1w → Renn Prime (K4w) – In the NGC 5248 galaxy. About 142 million kilometers above the north magnetic pole of Hemelein Prime. Not discovered in Hemelein Discovery. Intergalactic wormhole. The wormhole trip takes about 0.059 seconds.
2. S1w → Procyon B (K2w) – Discovered by Adele Watanabe during her survey of the system in Hemelein Discovery, though she did not transit the wormhole.
3. 4wa → –
4. 5wa → Polaris B (4wb) – Discovered by Adele Watanabe during her survey of the system in Hemelein Discovery, though she did not transit the wormhole.
5. 6wa → Saak (8wb) – Adele Watanabe originally entered the system through this wormhole at the beginning of in Hemelein Discovery.
6. 6wb → Procyon A (4wb) – Cellan Three. 6wb is located inside Cellan Three. Has been visited before, but probes were unable to figure out where they were due to the hemeleinium content in the enclosure.
7. 8wa → –
8. 8wb → –
9. K1w → – To Kimmalevoi space (unknown)
10. K2w → –
11. K3w → –
12. K4w → –
13. O1w → New Lehua (7wa) – Discovered in 4128 after the events in Hemelein Discovery.

Questions to be answered

1. Are there remains of colonies or facilities on any of the planets?
2. Are there other stations within the star system or nearby systems?
3. Come up with reason why no other aliens have explored and claimed this system. Legends, warnings, natural phenomena, etc. main reason below:
4. The closed off part of the station encloses a wormhole node. People previously had visited it but couldn't figure out how to get out, so never figured out where they were. The station was discovered from the outside through the discovery of a previously unexplored and undiscovered part of the wormhole network. There are 13 wormhole nodes in the system, but only 6 have been discovered (people only know about 5 because the one is inside the station)
