When I fast traveled to Lakeview, I heard armor running, so I was looking around(not moving) and I saw a mudcrab so I killed it attacking my Horse Carriage, then I saw an Imperial Courier(Hello again Ulfric!) so I picketed him for goods, nutttin, so I walked back, and I heard a sword on the ground, so I found an IMPERIAL SWORD! As you can see ^^^^^ I killed Ulfric, and the Western side of Skyrim recieved Minor conflicts, so I was extremely confused.
It should be past a small puddle with nirnroot in it. Its on the path where the carriage is, If anybody DOESN'T find it, can anyone explain why theres an Imperial Sword by my home?(no, I didnt pocket the Courier's sword)
