The manor of a Hlaalu noble, who runs the Mundrethi Slave Market next door. May have some (literal) skeletons in the closet, AKA connections with Camonna Tong from Andothren or slave smuggling rings.
A grotto entrance on an island in the Thirr River delta. Likely a smuggler's den given its proximity to two major ports (three, counting Vivec). However, might also have some connection to the ruins of Old Ebonheart, a Dwemer ruin, or a Sixth House base.
There are 3 separate plantations: Vathras, Mundrethi, and Oran. Mundrethi plantation also has a slave market.
There has already been some NPCing in this area, so existing dialogue and NPCs should be assessed first, to figure out what needs to be changed, removed or added.
Note: There is already dialogue and NPCs implemented in Almas Thirr. This claimer should check this over, and then add for any of the below topics that may have been missed.
