Where would you want to be positioned,
and what would you want him / it / her to do? ( optional ).
Iâd have me âTwilunaâ positioned at the hunters class order hall 
,
Maybe giving out a quest where iâd have a player go and do a /silly at other sad NPCâs to cheer them up.
I always wanted me as an NPC ( BM hunter) to be on those floating bits of land in the sky in Nagrand.
I guess to add a modern twist could add a side quest where I have a golf type stick with a couple of balls and you have to knock it through a few floating hoops that appear when you pick up the quest 
Iâd be a bartender.
Or an archivist.
I want to be a Nightborne NPC, greeting the new Nightborne players in the Nighthold the Nightborne starting zone. I do it even now, pretending to be a NPC, I stand by Thalyssra and say âWelcome adventurer!â it is quite fun how some people get confused lol.
Doesnât undead starting area have a questline like this? Its a silly and fun questline.
Back in the days when my rogue was horde i used to pretend being a npc or a random mob in the human starting areas. Quite the many got fooled and pvp flagged.
By the Auctioneer on one side, Mailbox on the other, crafting table to my left.
In the alliance base, defending the boss in some epic BG, or maybe some of the elite npcs that advance in Ashran when you conquest GY to aid your team.
Bard in an inn sounds about right.
Put my DK in ZulâDrak fighting off waves of enemies over at Zeramas.
Put my Paladin in Silvermoon over at walk of elders with a quest to tour the city.
Iâd be a male human, dancing on a mailbox in Stormwind. But in my panties would just be arrest warrants and restraining orders instead of cash bills.
My Robokiller would be found in Mechagon city in shady alleys.
he would be called âRobotic Killerâ (His full name) and would have a little rep and rewards! (Rep: Unknown (5.000) â Ally (10.000)-> Worthy Companion (20.000) that you get by eliminating enemyes (normal mobs: 100 èlite 500 Rares 1000 Wbs 5000)
he also would have a dialogue option and items to buy!
Only whoâm i find worthy will be able to know.
Iâm unit P3p, a small bird that built this robot to comunicate and interract with the world around me.
i would like that this would would be pure, and to do so, i need to eliminate the evil.
Will you help me in this quest?
he would sell only 2 items:
(250 gold)
Robo-tent: you place down a tent made with metal, with a mechanical Campfire and a little chest.
(300 gold)
friend Essemble: keeping this in your inventory will sometimes make Robotic Killer appear in the shadows near you (you and your group can see it only, and only you see it in m+, Raid and PvP)
A high elf bard in the snug harbor inn.
Or a night elf druid healing/giving the player character a quest to heal something together. Say, a npc who was hurt, or somehow repairing an ancient of lore/war, you get the idea.
Iâd be an hairstylist in a major city!
a questgiver near ironforge. i will stare at mountain around all day.
Id sit on top of the stormwind gates taking a dump on players walking into the city
Elrian, The Orc Slayer
Iâd be in BashalâAran, sitting in the Vicious Kaldorei Warsaber.
I would be the NPC that gives players the weekly quest to kill hordies, and also the NPC who talks to Alliance players when they fly over a PVP world quest.
Near Stonebull Lake, in Mulgore.
As a worgen could start in Val´sharah or The Emerald Dream with standing near the Scythe of the Wolf Pack
In the current expansion, near a point of heavy interest (Such as the AH, or the item upgrade NPC), but in a dark corner close by. Iâd also have a smol lynx pet.
âHello there, are you interested in my shady wares?â
Let me browse your goods.
Item list:
Felweed: 4g 20s (stacks of 5), makes your character feel high and happy for 5 in game minutes. Repeated dosage will increase the effects.
