Looking for Name of Scourge Hero

[tulee]

I am currently looking for the name of a Scourge hero. I do not know its name in Wow lore, but in a custom campaign, this model was used to portray him:

GhoulTinker

This icon was used to portray him:

(BTNAlvida.blp) cannot find it on hive.

And its name sounds like Magee or Mckee. Its title is either Contructor or Stitcher (like it creates monsters or something).
I tried to find it myself but failed. Would love if someone well versed in WoW lore could help me out. Thanks!

Are you sure it's not an original character? Could you give more details about it, like some story bits, who's it in contact with and so on?

That is a possibility. If people don't know it, then I will assume original. Only other relevant info is this hero is travelling with Darion Mograine (corrupted, not yet freed from Lich King's hold) and Siouxsie (who I had never heard of either, which is why I thought this hero might just be a lesser-known character). Their force name is Acherus Deathknights and they are cleansing the living who remain in Lordaeron.

Can't say it rings any bell and there aren't really any Acherus NPC that match this role, although the icon reminds me of Putricide from ICC and mobs sharing his model

Improbable candidates:
Obrahiim, the Traveler a skeleton architect.
Hargus the Gimp a geist doing repairs for death knights.
Corvus a skeleton siegesmith.
Edwards a wight squire of Siouxsie. (possible)
Patchwerk an abomination with a name and in a zone related to those two mentioned words: stitching and construction.
Archivist Zubashi a troll death knight related to tech.
Krick and Ick a leper gnome and his plague eruptor mountkick; somewhat similar in aspect to the used model but allegiance to Icecrown.
Shadow Construct a skeletal magician but in relation with Lady Alistra of the Ebon Hold.
Rottgut an abomination constructed by Lord Thorval of the Ebon Hold from various human, demon and night elf parts.

EDIT:
To add to @Chaosium:
Grobbulus was Darion's enemy in the Ashbringer comic and found in the Construct Quarter of Naxxramas.
