In this country the Queen is the true ruler so she holds power over king, but gives him authority to rule as he sees fit while she is away dealing with diplomatic relations. Towards the end of the series it rose up to be the powerful country of the world, not only because of the possession of four holy heroes but also because of their resounding victory against the former powerful nation of Faubley.
- Melromarc has the tradition of having the husband's name decided by the wife.
It is a matrilineal country under the monarch of Queen, who holds the high authority.
Melromarc's religion is the Four Saints Faith. But, the extremist faction that split from the Four Saints Faith, the Three Heroes Church, took over. However, due to their terrorist actions the majority of their members were either executed or imprisoned.
It was later replaced by Religion of four saint faith. Their first task was to correct all the misconception spread by the Three heroes church in regards to Shield hero and also to improve the relation between the Humans and Demi-humans. Unfortunately it wasn't easy as it seemed, as it took too long to overwright the centuries of three heroes church preaching and to mend the bad blood between the human-Demihumans.
In times of Trash Youth, Melromarc made its mark as a resourcefulness, as they ere able to defeat the mighty Silt welt which dream of world conquest. In times it went to down the hills and was fearing enemies, as they did all they could to prevent Nafumi to cross the border, fearing war.
After Trash reawaken his senses, they took down the powerful expedition of Faubley under Tact. Rising it's might to be the most powerful military of the world.
Though peaceful relation existed between them. It was completely stained after Melromarc summoned the four heroes against the international agreement. But the Queen agreed to the demand of king of Faubley winning the nation's support in the world conference for the time being.
It was again stain when Tact rose to power. He killed the queen of Melromarc and invaded the country. The heroes and Silt welt followed Trash plan to squashed it's army and took control of most of the Faubley land making Melromarc to be the powerful nation.
Melromarc and Siltwelt had a centuries of bad blood mostly because of the treatment of demi-humans in Melromarc.When Siltwelt desired for global domination, Luge of Melromarc halted their way. The queen of melromarc mended things with Siltwelt, by setting up a Demi-humans protected village in Melromarc while Siltwelt followed her example and set up a Human protected region in their land. This earned both nation a decade of peace.
But Problem again rose when Melromarc summoned the four heroes against the international agreement and to make the matter worst the treatment of shield hero enraged them to wage war. The Queen was able to diffuse the situation and things finally settled after she gained the trust of shield hero.
Silt Welt was upset with Tact's action and joined hand with Melromarc, surprising themselves for forming an ally. Their relationship was mostly mended except for the treatment of slavery under the pretext of fixing that in the future.They even gave their approval for the engagement of shield Hero and Melty, if woman from their land are permitted into Nafumi's harem.
Nothing much is mentioned about their past relationship. But they were infuriated by Melromarc for going against the international agreement. They were ready to wage war with Melromarc for their misdeeds against the shield hero.
They allied with Tact when he claimed himself to be the real hero. even though he stole the weapon from Naofumi.This earned them ire from the allied forces and the heroes.
They have a fairly a decent relationship. Zeltbull also helped Melromarc in shadows in times of Tact expedition.
