The Light Synthesis Civilization sought help from the Wandering Alliance because they indeed faced danger.
But this danger was not from an Alien Civilization; rather, it stemmed from internal disagreements.
Originally, after a war, nearly half of the one hundred Cosmic Battleships of the Light Synthesis Civilization had been lost, with the remaining forty observing the fierce battle between the two Constant Stars while heading out towards the Galaxy Nebula. However, not long into their journey, sudden issues arose with ten of the Cosmic Battleships.
Upon inspection, the Light Synthesis Civilization confirmed that these ten battleships had sustained some damage during combat, with critical engine parts suffering severe wear and needing replacement to maintain interstellar travel.
