The father that these two girls are talking about is the current patriarch of their family. Even though the elderly man had admonished and punished their father when he was young, he couldn't do that now that he has become an Origin god.
Royal families have a tradition of putting at least one origin god in charge of a family even though the highest power in the lower realm is the sovereign level or grand god. That's why their father is present in the lower realm.
It is true that when Origin gods are in the lower realm their power will be forcefully suppressed by the laws to the level of a sovereign, but there are some things that they can still do better than multitudes of sovereigns.
Several sovereigns can only hope to fight equally with a suppressed origin god, they cannot defeat one. The Origin god cannot kill them instantly, but he can suppress them easily.
The difference in power levels is why most sovereigns don't go to the upper realm unless they have powerful means of protection. To origin gods, sovereigns are like flickering candle flames, it would be just enough to sneeze to put it out. Coupled with the fact that only the best sovereigns become origin gods, the disparity in strength becomes even larger.
So currently the patriarch of the Volgori family of the Gemini race is their father. Even though their father seemed indifferent towards the outcome of the trial he is the most affected by it.
He has been secretly happy ever since he noticed some things from the soul lamps of the participants he sent off. He has long found out that his eldest children and some other people from his family bloodline had become Origin gods so he could leave.
He didn't spend a lot of manpower to meet the Survivors but he sent his daughters so that they could leave him in peace to pack his bag and put things in order for the handover before he leaves.
He had been alone for a while because he was a genius when he was younger so he did very well in the trials and won origin essence even though the cost was prohibitively high. When he became a sovereign he could become an origin god easily.
His twin had been the lucky one when they drew lots for who would stay. He didn't have anyone in his generation that became an Origin god to keep him company. So he stayed back in the realm alone.
When sovereigns leave the tower of heaven as Origin gods, they would change immensely. They would feel like the world was under their control, they only had to make their wish known and the world would change accordingly.
The future seemed to be looking up for them, but when they got back to their families they would find that they had to take up the mantle of the highest power. They could not leave until they too are able to raise talented juniors that would replace them.
It's not that they cannot create origin gods without the trial of heaven, even though it is difficult to acquire the cleaned origin essence of a fallen realm lord, for a family of their level the difficulty lies in actually finding the abode of a fallen origin god not in acquiring it.
But they don't create new origin gods with what they have gotten. It is because the approval of the realm is very important to an Origin god. There's no going back once you become an Origin god without the approval of mother high heaven.
The smallest consequence is banishment from the realm. You won't be able to return to the realm for whatever reason ever again. Other Origin gods will be suppressed in the realm, but you will never be able to enter. The greatest consequence is much worse than that.
Right now the current patriarch is writing down his final notes of advice and a list of the high-rank origin weapons and provisions he would be leaving behind. He would hand over the note with the mantle of patriarch and his good wishes before he left for the upper realm.
He didn't think his behavior is odd or inappropriate. It isn't that he didn't love his children, it's just that he is a little eccentric and his love for his children is not enough to keep him here in the lower realm.
Indeed, he had only given birth to them to ensure his chances of leaving for the upper realm soon, he had come to have feelings of affection for them due to fatherhood, but his children cannot hold him back. He didn't even put much effort into naming them.
Back at the tower where the people from the Volgori family are still waiting. Someone called out their names "Fhalemr(Light) and Ghemegr(Darkness)."
The guards standing around immediately tensed, they moved their hands closer to their weapons.
Even though fighting and killing around the tower of heaven are prohibited they can't be incompetent in their duty. They identified the source of the voice and it turned out to be two children.
They don't look like children but their voices sounded immature and it seemed from their appearance that they are from the supreme beast race. So the guards concluded that they must be children. Plus they had seen this duo before and recognized them.
Even though the call came from the kids the guards still didn't relax. It's because the two kids were accompanied by a guardian that is easily twice the average height of the Gemini. The two kids from the supreme beast race continued unperturbed and approached the two twin girls that had already been waving them over.
