Al-Niyat. The Name covers the asterism formed by TAU Scorpii and SIGMA Scorpii.
And if that's not enough, Al-Niyat has the Correct Number of Stars as shown in Derelict.
Tau Scorpii: Bluish-White B-Type Dwarf
Sigma Scorpii: Quaternary Syste,
S-Scorpii A: Bluish-White B-Type Giant + Yellow O-Type
S-Scorpii B: B-9 Dwarf
S-Scorpii C: Type Unknown
The one problem with this Theory is that Tau Scorpii is ~305ly closer than Sigma.
BUT - Sigma has FOUR Stars. So Derelict is likely set for the most part in Sigma Scorpii.
Since Al-Niyat refers to both Sigma and Tau, It doesn't take much of a Stretch to turn that into Tau Sigma
