This is Mount & Blade as you've NEVER seen it before. Southern Realms adds a lot of variety to the game, giving you more opportunities, skills, and... and I'll let the features list do the talking, since I'm rather chuffed with it myself.

Features:
- Map almost doubled in size from native, showing the Nord homelands, the mighty Empire of Gorinia to the south, and more!
- An extra 20 factions, each with new lands, troops, and heroes.
- Naval travel and combat adds a new dimension to the game; battle cutthroat Nordic pirates or the proud Alanian navy at sea with 2 different ship types and improved boarding ability.
- Foxyman's formations give you the ability to command your troops with deadly precision, but beware; morale failing is now a real problem that can crush the cohesion of your forces.
- Huge troop trees, including several non-faction ones.
- Religions; join the Orinite, Varalite, or Conirile churches to gain access to their holy men, healers, and (of course) battle-hardened religious warriors...
- Face enemies with powerful special abilities such as healing nearby troops, raising morale, or even regenerating health in battle.
- Become a Town Watch commander, with control over the defences of one of the many new or old cities in Calradia
- Hunt deer and boar for food or trophies; these latter can even be taken and sold to those who want them...
- New locations, including country taverns, two universities, and the rogue outpost at Jarren's rock
- Learn one of three skill sets, allowing you an incredible amount of choice in your character development. Either train as a barbarian with the Doaghan, or an Assassin in the alleys of Harlaushia, or learn the arts of command with general Tataca.
- Pubs are rather more interesting; meet the gamblers and drunks of Calradia, along with new mercenary forces that you can hire!
- A ton of other special features; villages now spawn refugee parties when burned, new bandit types roam the map, several companions require quests to allow you to hire them, and troops can be hired in city marketplaces.
- Other new features include shield bashing and spear bracing, both employed by the AI as well as your own forces.
- Did I forget something...?

Oh, and do please take a look at our forum; any feedback would be really appreciated. This is not a final version for the mod, though, so do be aware of that. Many thanks, and I hope you enjoy roaming the Southern Realms as much as I enjoyed their creation.
