The best reinforcements
All three groups had shortly started to move out as soon as Sunny's attack had begun. They felt like this was the best course of action. Not only would they catch the Dalki off-guard, but the general public who weren't taking part in it were also unaware of it.
However, out of all of the groups, one struggled to move out more than the others, and it was the Earthborn group. A Dalki fortress was set up on all the captured Earthborn planets. Even on those where the humans were currently still present, but the motherships had left a long time ago.
This caused frequent scuffles on the planets, with either side trying to hurt the other seriously. With the plan set in motion, the group relied on all of the attack forces to get rid of the Dalki on their planet. They would then set off and attack the other planets taking back what was once theirs.
