In the version of this Article originally published, the number of stars that can be attributed to Nyx with high confidence was given as 200; however, due to an error in the calculation of the probabilities of stars belonging to a particular kinematic structure, the number of stars is actually 90. As a result, edits have been made to the text of the paper and the relevant data in Figs. 1–3, and Supplementary Figs. 1–7 have been updated. The Supplementary Information PDF has also been updated.
