Edinburgh「エジンバラ Ejinbara」 was a kingdom, located within Britannia, that was taken over by the Vampire Clan when their seal was broken. It is located 186 miles east of Liones. It also serves as a prime location for mining minerals to make glass.
Before its destruction and overthrow, Edinburgh was considered a powerful kingdom with Holy Knights serving and protecting its people. Twelve years ago, the seal on the Vampire Clan was broken and the entire human population was either massacred or turned into vampires including the kingdom's Holy Knights. As it had a good alliance with Liones, Zaratras orders the Seven Deadly Sins to retake the kingdom and eliminate the threat of the vampires.
Upon arrival at Edinburgh, Zeldris and the Ten Commandments discover to their surprise that a castle was built on top of Edinburgh Hill, and are even more surprised to see that it is in ruins. Sensing the residue of an immense power radiating from nearby a really deep hole, Zeldris concludes that the culprit could only be Meliodas.
