Aldar is the father of the four powerful sons of Xerta galaxy. He started Xerta with first planet Ashenvil. It took him many years to generate enough energy to produce a reasonable size planet. Once Ashenvil was stable enough to start nourishing it with planets and small organisms he created his first son Otjin. He needed Otjin to help create many of the tiny creatures on Nanetara. Nanetara's planet life deeply plummeted. Otjin requested a brother to help with him on the climate and plant life of Ashenvil. Aldar granted his request and brought Rutmor.
