This is a sub-page of Xenoblade Chronicles.
The FLD_npclist.xls contains a list of all the NPCs in the game. The text in the rlt_job column is the description of characters that appears in the Affinity Chart. Despite not being able to add them to the Affinity Chart, many (often story-vital) NPCs on the list have a description, and it's likely the developers also used them to label NPCs for reference.
