There are four goblins in the fireworks business with the surname "Sparks" that appear to be related:
- is a year-round Fireworks Vendor in Booty Bay in Stranglethorn Vale
- is a Holiday Fireworks Vendor in Orgrimmar in Durotar
- is a Holiday Fireworks Vendor in Ratchet in The Barrens
- is a Holiday Fireworks Vendor in Booty Bay in Stranglethorn Vale
Not as compelling is a possible fifth relation with this NPC, Lee Sparks, who is not in the fireworks business and is newer content. His surname is a reference to an actual person's name (see trivia) rather than a fireworks pun. It is likely that the surname being the same is just a coincidence.
This character and his title, "The Taskmaster", probably refers to one of the Burning Crusades producers, Lee Sparks.
