Skyrim feels empty until now. This mod adds new factions. All citizens throughout skyrim can rest assured that their  Towns are  now guarded byElite Archers, cross bow women, City guards and Town Guards.  Every Bridge how has a bridge keeper and 4  guards.  Major cities such as Solitude now send a group or rangers, knights and squires to the lesser cities such as  morthal and Falkreath.   There are a group of merchants that travel from hold to hold  each has a group of guards to protect her from thieves and bandits.  Imperial soldiers and Stormcloaks travel from their military camps to a fort on  a hold  on the opposite side of skyrim. Out of each town a group of Bandit hunters attacks notable bandit forts scattered throughout skyrim. These groups are the  friendly ones.
There are more bandits at each bandit fort. Now when you approach robbers gorge you will be greeted with a rain of arrows.  All the towns are raided by bandits who come from fleets beyond the North Shore.  Scattered throughout skyrim  there are stockades full of Amazon warriors who hate men with a passion.  They leave the stockade once a week to raid villages and cities. 
Last but not least if you ever felt when a Dragon appeared  that you could focus on the dragon alone you are gravely mistaken. Now those who created the Dragons and all life in the universa have arrived.  You will find  forts scattered throughout skyrim full of Draconian warriors who are allied with the Dragons. This means that even in the first dragon fight  at the Western Watchtower there is a chance a group of Draconian will drop in and assist the dragons. Draconians have more health than any other creatures. They also wear dragon scale armour and use Ebony weapons.
All groups mentioned have the ability to heal themselves and their companions. Now skyrim will be the exciting place it should be.

The optional files are other mods I created in order to complement this one.  Warrior girls adds 5  hot female companions who fight as good as they look. You can find them in Riverwood,  Windhelm, Riften, Solitude, Whiterun, Falkreath,Markarth, Morthal and Dawnstar. Be kind to them as they feel hopeless and need a hero to lead them  to glory. They are marriageable and level up with the dragonborn.  Do not let their hot looks and ragged clothes fool you. These girls can give a dragon a run for its money.   What better way to reward these beauties than to   give them a proper home .
Slave Pit adds a player house in each of the holds.  As you enter one can be amazed by the  tremendous hot tub.  There is a merchant, a bard and a few maids who tend to be lazy but I think you can find something to do with them. As you go down the hall you will approach the smithy where you can  create all your weapons  armour, and potions. There is enough storage and of course a few lazy maids and a group of bards who can keep you entertained.  As you continue down the hall you will come to an intersection. On the left is your very own kitchen. You will never again complain about not enough kitchen space. If you go to the right you will come across your  master bedroom.   All the maids sleep behind the small partitians but if you need anything whatever it might be  they will happy to assist you. You also have a merchant and a group of bards.  Do not worry about someone breaking in because your fortress guards will take care of that for you. If you went to the end of corridor you will see a door.  If you enter you go to the lower level.
Here are your arenas and prison cells. If your maids will not dance as you requested you can dump them into the pit for the entertainment of the chaurus , sabrecats, spiders, wolves and bears. You could also lock them up for a while . Do not worry as prison guards will not let your prisoners escape as they guard the entire dungeon area.  
     This mod works great with mods such as Paradise Halls, Estrus Charus, arousing attire and armours, CBBE, animated prostitution, Defeat, and Amazing follower tweaks. Not only do you now have a place that you can spend with those gorgeous warrior girls frolicking in the hot tub but you have a place to sell and protect your loot.
    This new update adds rangers into the forests. They will always help the dragonborn when he is in trouble. The bridge guards, elite guards, and city guards are now marriageable and are allied with the player.  There are now packs of Wargs and chaurus who roam from the North to the South looking to cause havoc where ever they go. Be aware of the hell hares. Though they are not hostile to the player they now will fire fireballs at who ever attacks them.
