The ruins of the castle sat silent and abandoned by humans. Half of the structure was still intact and albeit in ruin for the shattered windows. Youth and the misguided believed themselves brave to get within a stones throw of the castle. Young Kaguya thought it a sign of their bravery to challenge the master of the clan there. Yet he did not show for petty squabbles or the weak. He did not seek retribution for he did not care for material things. The castle was the same to a being like him. He need not sleep or eat. He needed no shelter from the elements. After all he commanded them. Still that half the castle was mostly wholly intact. Albeit the dust and webs had settled in over the surfaces. However the other half of the castle people avoided. Here was the remnants of a battle for the last true challenger. A student of Sero's had come and challenged him to a duel once upon a time. Their fight had torn apart the castle with large scale jutsu. Smashing through even the Kaguya bone structure. Now its shattered remnants looked more like a cave. Halls with no roof had pooled rainwater and gathered moss. The scorch marks could hardly be seen.
Here Sero sat within his domain. Deep within the ruins where the majority of the blackened scorched bone was. No moss gathered here and a mist hung about the grounds. Here in the audience hall burnt to a crisp save a single throne sat Sero in his human guise. Purple eyes flicked to the training he was preforming behind long black hair. His form was adorned in black robes that seemed to sink into the shadows around him in the dimly lit room. Here the abomination sat in training until another threat such as the bijuu arrived. He had an entire division of ANBU he commanded for the normal people. Criminals and such he mostly used for training purposes now. A nation level power now reserved himself for training these humans with promise and eliminating the grander threats. Before him he was practicing utilizing all his elements at once. Four orbs hung in the air in a slow circle. His hand gripping the hilt of the great sword for even further control over his flames. In a circle beneath the ceiling four orbs rotated. Evenly spaced out and perfectly shapes. One of white wisps of wind. One of coils of bone grinding into itself. One of water surging in rotation and one of calm, purple flame. A practice in chakra control to perfectly control four elements at once and hold it.
