Star Trek Lower Decks: Every Easter Egg & Hidden Reference From 'Envoys'

As Mariner, Boimler, and K'orin descend towards the surface Tulgana IV, we see the city has a large white spire in its center. This spire is similar to the one that distinguished the advanced Farpoint Station from the more primitive Old Bandi City in TNG's pilot episode "Encounter at Farpoint".

This establishing shot also shows four locations Mariner and Boimler visit in their search for K'orin – counterclockwise there's the Klingon District, the Risian neighborhood, the Andorian District, and the Federation Embassy.
