We need a sequel to The Crystal Star, with Waru returning to the GFFA with an invasion force of fellow Warus seeking to destroy the Force and replace it with the Anti-Force of their universe to facilitate colonization. Use the opportunity to introduce the greater SW Multiverse, with an entire fleet of Death Stars, Darksabers, Starkiller Bases, and Suncrushers gathered from every timeline to fight the extradimensional slabs of giant scaled meat.
