The 2008 "Terra" miniseries had intended to explain that Terra was driven insane by an element called "quixium" harvested from Strata, which had been used by Markovian scientists to grant her earth-based superpowers. With a year-long delay in the publication of the "Terra" miniseries and the interim release of "DCU: Last Will and Testament", this plot point was dropped completely. According to Justin Gray, "Terra 1 stays as she is in LW&T. The brain damage was part of the initial story (before LW&T) that connected all three Terras and Geo-Force to Strata, the book needed to be changed to reflect LW&T, the double ship made changes to issue #2 impossible. It happens and we all did what we could to make it work."
