The Tudor Empire is an empire possessing the strongest military on the continent, taking Doldrey as a foothold during its Hundred-Year War with Midland. However, when civil war breaks over the line of succession, Tudor is forced seek peace with Midland after the siege of Doldrey. Years later, Tudor has amassed its forces to protect Vritannis in the Holy See Alliance.
Tudor's military forces are easily recognizable by their heavy arms and armor – its professional soldiers, especially knights, along with their horses, wear heavy armor and use heavy weapons. Furthermore, each order of knights has its own recognizable style of armor, with the armor of the Black Ram Iron Lance Knights being adorned with ram horns, the Blue Whale Knights decorated with fish scales, and the mounts of the Purple Rhino Knights bearing horns on their chanfrons.
The empire's forces include:
- Black Ram Iron Lance Knights
- Black Wolf Knights
- Blue Whale Knights
- Holy Purple Rhino Knights
- Scorpion Serpent Knights
- "Tudor" is translated as "Chuder" by Dark Horse Comics.
