Prior to the Imperial colonization of the original Argonian city of Lilmoth, it was ruled by Argonian priest-king and queens. The earliest record of an Imperial sovereign in the city dating to 3E 109 when Magnus Septim wedded the Queen of Lilmoth, Hellena. Lilmoth had previously been sympathetic to Cyrodilic interests even before its colonization during the Third Era, as far back as the Reman Empire and its war with Morrowind, with the warlord of the city of the time, Ulaqth, leading troops into battle against the Duke of Mournhold. The only other recorded warlord of the city was a warlady called Ioa. In the early years of the Fourth Era, Lilmoth fell victim to the floating city Umbriel. This event is known as The Slaughter of Lilmoth. This was one of the most gruesome massacres in all of Tamriellic history. This was also the place where both Annaig Hoinart and Mere-Glim, two friends who lived for a time on Umbriel, were born.
- Lilmoth shares the name with the race of beastfolk known as Lilmothiit, indicating a possible connection.
