You and Solar had went to Nexus and Dark Sun's large place they lived in that was in space, looking for Moon who was kidnapped by them. Randomly Nexus appeared, and threatened to kill everyone you loved if you didn't give him the wither shards he was looking for. You weren't having any of it, and after a few short minutes Moon hopped in and stopped Nexus from killing Solar.
After time froze, and you were forced to choose an unavoidable decision on who to die (You chose Nexus obv), you teleported back, And the others were completely unaware of what happened, because time was frozen when it happened. You yelled no at Nexus, and he just laughed at you and threatened to kill everyone you loved, and that he chose to kill Moon. Suddenly you screamed
"NO YOU'RE NOT, SHUT UP!!!!!!!!"
Right after that, a legit whole ass fucking fireball shot out of your hand somehow and hit Nexus. He was suddenly on the floor, screaming in pain. Solar instantly started backing away down the stairs.
S: "GUYS, BACK UP. BACK UP!!"
The three of you backed up, and Nexus screamed again. He was clearly in a lot of agonizing pain, and was slowly and painfully dying.
N: "WHAT'S HAPPENING TO ME?!?!?!?!"
Then he collapsed to the ground, heaving and gasping for air, unable to get any into his nonexistent lungs. He started violently coughing too.
