An intruder
With war having been declared, all of the planets that the human race lived on were on high alert, especially those in the Graylash area. The Dalki had been making very strange movements from what they had been able to monitor.
Bit by bit, they would be testing the waters, as small scuffles between certain spaceships, as well as on orange portal planets had occurred. There was a reason why the human race wasn't so quick to give up the beast planets and were still hunting for beasts daily.
For one, they acted as the fuel for the powerful Mechs that would be used by those who weren't strong ability users, giving them a fighting chance against the Dalki. The second reason, which was true for both sides, was they would be used to power their spaceship's weapons.
