Ghorion was once one of the Three Troll Kings of the Cloudsteeth Mountains. Undeath has only made him crueler, and much, much more powerful.
They were formidable even before they learned how to use weapons.
Nahactl, the Wanderer
The Trollshaw Staff is roughly six feet tall, though if the bends in the wood were pulled out straight, the staff would easily be eight or nine feet tall. As it is, it is twisted as a troll itself.
"...the city was built on many levels, linked by stone bridges. But with the improvements in diet and corresponding increase in stature and strength of the populace, these bridges became too low, and the people would hit their heads. The bridges were eventually done away with in 1764, but the scars on the walls where they once jutted out remain, and in Low Bridge Street there is still one extant bridge, measuring about 6' high." - Chronicler Rasill, Mondopedia, Vol II (The Lands of Hyellia)
