At the entrance of the Weidete Castle, there are merchants who have set up shop in front of the castle gates to cater to visitors to Weidete, forming a commercial district. Most of them are hybrids with ominous and malformed fervor genes that were never seen in any region of Hellmarsh. Additionally, there is the Sea of Forgetfulness called Sidhe, which appears like a giant spider web composed of fine cobwebs and roots of Silbadu, spreading widely from the center to the surroundings. There are also ancient barges, now tombs, hinting at the presence of ample water in the past, evidenced by large dark-red puddles scattered around. Sidhe is an area with a cold and scary air where blizzards rage, and are inhabited by vampires, especially among the demons, who are known to parasitize blood along the veins of contracts with other races.
