This is just a port of HorribleAndy's mod of the same name.   He is in no way responsible for this port nor did he have any input into the porting process. 
I added the esl flag as well as created a patch to be compatible with TheOscar0's The Dark Brotherhood Initiates, Pandorable's Initiates and USMP.  There are two main files, both esl flagged.  One requires USSEP, the other does not.  All patches require USSEP.
I changed the names of the two initiates to Harlend and Adelinda for consistency with the Dark Brotherhood Initiates.


DESCRIPTION

• If attacked by a Dark Brotherhood Assassin, you can now take their Armor when looting the body.
• Shadowmere now has 250 speed and 500 Stamina. He is from the Void, so increased stats seemed appropriate.
• Spectral Assassin is now called Lucien Lachance.
• Lucien Lachance is now red.
• Lucien Lachance has new Spell art.
• Lucien Lachance now armed with Daedric Dagger rather than Steel. A dagger from the depths of Oblivion seemed more fitting.
• Lucien Lachance has more Health. He is from the Void, so increased Health seemed appropriate.
• TB Gloves have new enchantments.
• Cowl/Armor/Gloves have new enchantments.
• Hood/Robes/Handwraps have new enchantments.
• New enchantment on the Nightweaver's Band.
• DB Forever moved to Misc. section of journal.
• Contracts from the Night Mother are worth more Gold.
• Added an Ebony Bow, Ebony Dagger and 25 Ebony Arrows to the inventory of the Ancient Assassin.
• DB Initiate 1 is now named Harlend. His inventory is 1 Elven Bow, 1 EbonyDagger, 50 Elven Arrows. Set to Protected. He has the ability to dual-wield (will only do so while in combat). Has 'LightFoot', 'SilentRoll' and 'Stealth40' Perks. Moves back further when bumped into.
• DB Initiate 2 is now named Adelinda. Her inventory is 1 Dwarven Bow, 1ebony Dagger, 50 Dwarven Arrows. Set to Protected. She has the ability to dual-wield (will only do so while in combat). Has 'LightFoot', 'SilentRoll' and 'Stealth40' Perks. Moves back further when bumped into.
• Cicero has 'Light Foot', 'SilentRoll' and 'Stealth40' Perks. Moves back further when bumped into.
• Added a Khajiit fence named J'fiir to the Dawnstar Sanctuary.
• De-cluttered the Dawnstar Sanctuary. You just spent all that Gold to get the Sanctuary outfitted, why would it be so dirty?
  

INSTALLATION

• Put file(s) in data folder or install with your preferred mod manager.
  

ADDITIONAL NOTES

• If you have any DB related Armor on, please un-equip and re-equip for the
  new enchantments to take effect. This is because Skyrim's engine has problems recognizing new enchantments if an item is already active. The same may be true for Lucien Lachance.
• Optional file for re-textured robes for both male and female. Full weight slider support. All races supported.  (LE version only)
• Optional file for re-textured Night Mother. (LE version only)
• Mod cleaned with TES5Edit before being published.
