A small pun on the Christmas song "Silver and Gold" and the numerous, shiny/smooth studs that come with Orc Forge. Put them together, and voila! Christmas Orcs!
Here we see Lurtz and a minion have infiltrated a Christmas tree farm, and have taken the liberty of decorating the nearest tree.
Lurtz puts the star on the tree...
...while his Orcish friend looks on with the sack of ornaments.
A job well done, boys. Merry Christmas (from me and the Orcs)! :D
