Dolph (once known as Michafute) is a member of the group of assassin called Nether Gate. As a member he is highly trained and was close to Mismar. During the war between, Shahrewar Falenas and Falzrahm Falenas, Dolph killed Marscal Godwin's wife, named Rosalind Godwin. After the disbandment of the Nether Gate, Dolph was took by the Godwins and to repay them, Dolph became the personal assassin of the Godwin.
Dolph is a man who prefer himself to be clean and tidy. He is always calm and well mannered. He is concern on his effectiveness in battle and he is ready to use a drug to increase his strength.
Before the Sun Rune War, Dolph is seen in the kidnapping event of Marina, he is the one who gave Dark Arcanum to Marina. When the Godwin attack the Sun Palace, Dolph see that the Dark Arcanum they put on the food at the engagement ceremony failed because Lyon know's the antidote for it. Dolph and Childerich attack the escaping Prince Freyjadour Falenas and Sialeeds Falenas, but Kyle and Zegai fought them to give way for Freyjadour and Sialeeds to escape.
During the Sun Rune War, the Godwins plan to terminate the Beavers so they sent Dolph to assassinate them but Freyjadour came and protect them. During the siege of Doraat, Sialeeds told that she will join the Godwin side. At the Queen's Campaign, Dolph plan to prevent Lymsleia Falenas to reach her brother and Dolph stab Lyon giving her a mortal wound, because Dolph thought that injuring a member of the Loyalist Army lessened the risk of being pursued by the Loyalist Army's member.
On the Ashtwal Mountains, Dolph protects Marscal and stop Freyjadour and Lyon to proceed deeper. Lyon fought him on a one-on-one duel, but he was defeated. Even though he was defeated, Dolph was still able to fight her because of the drugs he used. When Dolph is attacking Lyon, Freyjadour pushed her out of the attack and used the Dawn Rune to totally defeat him.
