Marscal Godwin is the main antagonist in Suikoden V.
Marscal is the head of the House of Godwin, he is one of the most powerful and influential nobles in the Senate. He is the father of Gizel Godwin and Rosalind Godwin's husband. They are based in Stormfist.
The rivalry between the House of Barows and the House of Godwin created misfortune between the two families. Salum started to worry about the reduction of their influence when the two male members of the Godwin married to both Queen Olhazeta Falenas and Princess Shahrewar Falenas and due to it Salum influence Princess Falzrahm, the younger sister of Shahrewar and the wife of Kauss Barows to take the throne for herself. This started a war between the two sister and it lead to Mardas Godwin and Rosalind's death.
Marscal is a militant man who believes that the only way to have successful country is to have unrivaled military strength, rigid order, and centralized government.
Before the Sun Rune War, Marscal host the Sacred Games because it taken place in the Stormfist. Gizel is one of the applicant for the Sacred Games, so he plan to remove the Zegai the Barows gladiator in order to win.
During the Sacred Game, he see Prince Freyjadour Falenas aspect as a problem in the future, so after seeing the royal family leave the Stormfist, he warn Gizel about his schemes might work in the short term but he may be planting the seed for future problems.
Marscal didn't come to Gizel and Princess Lymsleia Falenas' engagement ceremony, but came when Gizel successfully took over the Sun Palace, but came early feeling worried about the outcome on Gizel trying to equip the Sun Rune. Eventually Gizel failed to bear the Sun Rune.
During the Sun Rune War, instead of taking care on how to assassinate Freyjadour, he focused himself on the Sun Rune and he recruited many Sindar scholars to study the rune. The scholars had successfully discover on how to use the Sun Rune without equipping it into the human body. Marscal uses the Sun Rune in order to destroy the Sol-Falena's southern dam to wash away the Loyalist Army, but he failed when Sialeeds Falenas counter it. After this, he fled to the Ashtwal Mountains.
As Freyjadour showed up with Lyon in Ashtwal Mountain, he told that the reason their side lost is because he underestimated Freyjadour and the reason why he melted the glacier was to lead the Freyjadour and his Loyalist Army there. He also had no intention of flooding Falena because he love Falena as much as they do. The reason why he killed so many people is because he wanted Falena to be strong and prosperous country but he thinks that they became spellbound by the power of the Sun Rune before they realized it. They started to think that justice was on their side, and that it was all right to destroyed anyone who disobeyed. Just like Queen Arshtat Falenas.
Marscal also told that he is not saying those because the Sun Rune bewitched him and it's more like he chose to let the Sun Rune's power intoxicate him and in the end he lost. He asked Freyjadour if he can really say that he is different from them and can he swear to pass the Sun Rune on to the next generation without getting lost in it's power. After Freyjadour swears that he can, Marscal use the power of the Sun Rune to summon the Sun Rune Incarnation to prove it. Marscal body is gone after summoning the Sun Rune incarnation. Marscal is seen in the ending sequence silently saluting Freyjadour.
