Salman was once known as "Salman the Onslaught," famed for his exceptional skill and lethal precision with a spear during his prime. His formidable combat prowess often decided battles with a single strike, earning him widespread fear and respect. He served the Houtman family for many years, knowing Fena Houtman from her childhood.

In his advanced age, Salman suffered significant physical decline. His legendary spear skills faded until he struggled against ordinary soldiers. He lost teeth, causing difficulty in speech, especially with sounds like "s." Despite these limitations, he retained his wisdom and deep loyalty to the Houtman family.

When Fena was held on Shangri-La, Salman and fellow knight Otto orchestrated her escape. They readied a raft on the eastern coast to flee the island. Their journey ended upon reaching Goblin Island, where Salman and Otto concluded their active role in Fena's quest. Throughout this endeavor, Salman prioritized Fena's safety with unwavering dedication, demonstrating his protective commitment despite his diminished capabilities. His transition from a feared warrior to a protective elder underscores his enduring loyalty to Fena and her family across his life.
