There are several lines added to non-Vvardenfell NPCs by TD that either do not fit any context besides the DLC they came from or are simply annoying and stupid.
TR_OW06_Plantation_01 Plantation manor of a noble Hlaalu family. Include private quarters, a dining area and an office. Include a small bedroom for a servant.
TR_OW06_Tomb_llethri Llethri Ancestral Tomb Medium Ancestral Tomb of the Redoran Llethri family. Not visited, but well protected by ancestral guardians.
