What are NPCs have no job, aren't involved in any quests, and you can't trade with?

Question

I want to see which NPCs are kinda just there and we don't know why type of ordeal.  Please tell me what NPCs have no job, aren't involved in any quests, and you also can't trade with them. It would be great if you could list their location so we can go interrogate them if needbe. Thanks in advance.

Answer 1

It would be a big list to come up with all these NPCs and the list is constantly changing. Just because an NPC is not part of a quest now or does not buy/sell any items doesn't mean that they won't eventually in a future update. I would recommend looking on Tibia Wiki under NPCs (https://tibia.fandom.com/wiki/NPCs). They have many filters you can do based on city or what job the NPC has.

To come up with the list you are asking for I think your best bet would be to use this list https://tibia.fandom.com/wiki/List_of_NPCs then sort by the Buy/Sell column. You can then look through NPCs and skip over any you are not interested in based on their job. Also, if you open up an individual NPC there may be a spoiler tag. If you expand this it will notify you if they are part of a quest or not. 

Answer 2

I'm going to make a chart of all the NPCs that apparently have no job, aren't involved in any quests, and you can't trade with. However, keep in mind I believe some NPCs in-game are meant to be apart of a story but not a quest. Maybe some NPCs are just there for fun like apparitions, but I'll include those anyways. The NPCs that I think are mysterious I'll mark with a * Please note I'm going based off of what my sources help me with.

NPC	Location	Details

Willem	Island of Destiny	Willem is an apprentice to Narai and loves everything about being a paladin. When you greet him, he will immediately ask for an apple, which he wants to shoot from your head. This makes him an obvious allusion to marksman William Tell, who once shot an apple of his son's head.
