To begin the journey, seek out the Balanced Scales Pub in Hla Oad.
From the readme:
== ABOUT ==
Balanced Scales adds a faction (“Argonian Hunters”) whose sole mission is to rid Vvardenfell (and, in a large sense, all of Tamriel) of the plague that is the Argonian species. All those free of cursed Argonian blood are free to express their interest to Saren Andrethi in Hla Oad. Be warned: the path to ridding the land of the Argonians is fraught with danger, and the machinations of forces unseen will challenge all that you are.
New guildhalls are in Hla Oad, Gnaar Mok, Suran, and elsewhere
Various new caves have been added.
Scores of new NPCs
New ingredients
NOTE: This is a Beta release. While more-or-less feature-complete, there are definitely bugs which we don’t know about (and some that we do). We hope that these are all minor and don’t detract from your enjoyment of the game. However, if you do find bugs and/or think you are unable to progress in the missions, please let us know so we can help you and make the mod better for the final release.
We'll read everything you say, so anything helps.
