King Mathias ruled Morcia for many years before Vladek took power. Mathias was thrown in a dungeon and Jayko, Danju, Rascus and Santis went to rescue him. Vladek was eventually overthrown, and Sir Jayko became the new king. In 2006 two new knights were introduced called Sir Kentis and Sir Adric who were rookies assigned to help. Vladek also now has two minions called Karzon and Dracus. Vladek was not able to beat the knights and retreated with his Shadow Knights.
Morcia is a land with varied terrain. At the south-west the country borders to a large body of water and features a curved shoreline with a peninsula and a bay. The north-western border is formed by a large mountain-range with a large swamp (the moorlands) to the south which is crossed by a rope bridge. Another map shows this swamp to be further to the east, while the "moorlands" are still at their former position.
According to the map shown in the building instructions, the two largest buildings in Morcia are the Castle of Morcia and the Citadel of Orlan that are situated at the north-eastern border and next to the shore respectively. South of the castle lies a plain were the Grand Tournament took place.
Through the western part of Morcia runs a river that comes from the northern mountains. It runs through the swamp, exits it at the south and later passes the Citadel of Orlan as it forms a waterfall. It then runs through the peninsula past the provinces Banteras and Talonjay before it finally flows into the sea. Other provinces are Aldendan, to the north of the castle and Orkosan at the eastern shore of the large bay (2004) but was shown to be on the other side of it in 2005.
Morcia contains four provinces each of which is the home of one of the four original heroes from 2004. The four provinces are Aldendan the home of Danju, Banteras home to Rascus, Talonjay the home of Jayko and Orkosan the home of Santis. The castle of Talonjay was included in the set 8799 Knights' Castle Wall.
Animal-themed castle concepts
Original designs included animal themed castles for the heroes. Santis' bear-themed castle was set in the mountains between Morcia and the Wastelands. The first design was set high in the mountains. Then it was changed so the Castle defended the path into the Wastelands. It was then repainted. However, it was later changed so that Santis came from Orkosan, a farmland province. Castles for Danju (wolf-themed), Rascus (monkey-themed) and Jayko (hawk/eagle-themed). None of these concepts were ever used in sets,however.
- It is possible that the name "Morcia" comes from the real kingdom of Mercia.
