The True Martial Island is a Sea God Lineage created by True Martial Sea God at the start of the Emperors Era. It is considered to be among the strongest lineages of Sea Demons, but it have always been very low-key and rarely showed itself to the world. Because of this, few had seen it in person.
The True Martial Island is a huge island with rolling hills and animals. The highest peaks were covered with mists and clouds as waterfalls ran straight down to the bottom.
