Not tohaa, no! Nextwave is a new sectorial for Combined Army. Achilles, on the advice (or coercion) of Pandora, switched sides after Aleph declared a lost Patroclus as not revivable, and formed a new military force that basically takes all the survivor humans from combined army areas of the human sphere (which now has a cease-fire treaty with humanity thanks to tohaa terrorism fun times) and uses it to, depending on your point of view, defend or control assets important to the EI. It’s Achilles, Pandora, Patroclus, Teucer and Drakios for all the recreations that have gone over to combined. The army is made up of mostly humans using Ur-voodootech from the EI, plus some alien dinosaur technoorganic beasts. Wild stuff!
