Grug

There is some argument regarding what this towering creature actually is, but Grug himself insists that he's an orc, and nothing more or less.
The monosyllabic titan stands at least head and shoulders taller than most other residents of Greenskin House and is almost as wide as he is tall. He wears a rough patchwork of heavy scrap iron, with suggestions of coarse leatherwork and random furs padding underneath.
Often assumed to not be paying attention to his surroundings because of the faraway, unfocused look on his face, he actually retains a surprising amount of information, and can unexpectedly offer razor-sharp insights, although tinged with a brutal and abrupt view of the world.
Rumor has it that he's a Cleric in training, although when asked he can't seem to keep consistent about his deity's name. Sometimes it's Gork, other times it's Mork, and people find themselves wondering whether more gods will pop out of the woodwork soon.
