A ''Wurmian'' is a species not unlike humans that inhabit the world of Wurm. Players control a Wurmian in their adventures, and NPC Wurmian tower guards, merchants and traders inhabit the world with them.
A Wurmian has several characteristics that are different to a humans. The greatest example is the averageweight average weight of 90kg; larger than that of a human. (Combined with the 1.8m height, this gives the Wurmian a high BMI, if compared to a human. Not that BMI is a good measure, but it does imply either above average muscle or fat mass.) Wurmians are also much hardier, being able to withstand and heal from powerful attacks, go long periods without food, and after training and exercise, carry gigantic loads and swim vast distances. Wurmians also have other strange characteristics, they expand in size when they die, and they posess the ability to channel magic.
Wurmians are known to have existed in a relatively civilised state upon their planet for at least 1000 years, before which all records are destroyed by the fire at the Library of Sorrow.
