This is a page on the Tomek series universe.
The orwallin people originated on the planet Orwal. Adults stand three to four meters tall. They have a muscular humanoid profile with two arms, two legs, a tail and a head on top. They are covered with cream colored scales and no hair. The head is shaped like a cross between human and snake. Their eyes glow a faint green.
Their culture requires that orwallins cover themselves with a long brown robe and hood that hides most of their body. Most orwallins follow this rule faithfully, though they sometimes vary from the standard color and style.
Artist depictions vary.
