A planet that hosts an annex of the Daystrom Institute, the facility to which Admiral Haftel sought to remove Data's daughter Lal in 2366.
Galor IV is a Federation planet on which the Daystrom Institute maintains a research annex devoted to cybernetics. It is discussed in the third-season Next Generation episode The Offspring.
In 2366 Data builds an android child, Lal, using a new technique he learnt at a conference. When Starfleet Research hears of it, Vice Admiral Haftel insists that she be transferred to the Galor IV facility, where specialists could oversee her development away from the distractions of a starship. Data and Picard object that she would be separated from her only parent.
Haftel comes aboard the Enterprise-D to enforce the order. The fear of being sent away triggers an emotional response in Lal that her positronic brain cannot sustain, and despite the admiral's own efforts alongside Data she suffers a fatal cascade failure.
