One of them
With the simultaneous Dalki attacks going on everywhere, all three main factions were suffering. The battles that were being held in space, soon went toward the planets. It seemed like the Dalki weren't really fond of space combat either as they believed in their own physical prowess.
It had been the same back during the first war. A large mothership, black in colour but odd shaped like a blimp had been used to reach Earth. Whatever attacks they had used against this mothership had been ineffective. Once that large ship had been close enough, it had fired out several black pods to invade their homeplanet.
It was nearly the same this time, the main difference was that the pods were landing on the beast planets instead. Having to evaluate everything that was going on was Sach, the new Supreme Commander. The giant Bertha ship had drifted towards the centre most planet of all those that belonged to their group at the moment.
