A ''Wurmian'' is a species not unlike humans that inhabit the world of Wurm. [[Player]]s control a Wurmian in their adventures, and [[Wikipedia:NPC|NPC]] Wurmian tower guards, [[merchant]]s, and [[trader]]s inhabit the world with them.
A Wurmian has several characteristics that are different to a humans. An example is the average weight of 90kg; a somewhat high weight against that of a human, especially when dealing with female wurmians, who differ little to males in weight and strength. (Combined with the 1.8m height, this gives the Wurmian a high [[Wikipedia:BMI|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 posses the [[Religion#Priest_and_spells|ability to channel magic]].
