Coincidentally, Dada Niel currently lacked enough military strength.
So the parties quickly came to an agreement—the High Tower Council, ARC, and War Planet provided Dada Niel with troops and weapons, while Dada Niel handled the reconstruction of their three planets. According to reports from Dada Niel's side, the reconstruction of the planets was progressing smoothly, only Dada Niel was still considering whether to relocate some of the population from the human civilization planet he controlled to these three planets.
After all, these three planets were currently sparsely populated; the indigenous people had either been bombed by the Cabal, killed by the Mars Demons, or nearly wiped out in the Orc wars.
Moreover, it so happened that the population on Dada Niel's own planet had indeed exploded—after all, Duanmu Huai had seen that planet, it was as crowded as a hive. Pandora could have been a good choice, if only its atmosphere had been suitable for human habitation.
