The East Empire Company is the well-known Imperial shipping organization and has spread its influence across Tamriel.
A few years prior, the company made its first in-roads in Skyrim by establishing an office and shipping center in Windhelm. The organization enjoyed a brisk business here, in direct competition with that of Clan Shatter-Shield’s, but the office is now closed. It can be reopened as part of side quest "Rise in the East."
The East Empire Company has trading offices both in Solitude and in Windhelm, but they are currently having difficulties maintaining their presence in Windhelm because of harassment from a group of pirates called the Blood Horkers. Orthus Endario, the leader of the East Empire Company office in Windhelm, wants to shut them down so he can be back in business and asks the Dragonborn to help.
