Stalas stares at her maps in fascination.
He kneels in the road next to the four boxed maps, takes off his gauntlets, traces the lines with his bare fingers, and then seems to visualize a sphere in the air over the four circles, making gestures as though picking them up and wrapping them around it.
(Part of his right hand glows blue-white in a way that would indicate a really nasty bruise if, as seems to be the case, 'glowing blue-white' is the colour of his blood. He pays it no mind.)
When he's satisfied himself that the topology checks out, he puts his gauntlets back on and draws a circle, in which he sketches the shape of the continent from Tev's map. Then he boxes that single circle. The continent he names 'Thedas', and 'continent', with reference to continents depicted on Ambela's four-part map of Valinor to define the term; then he defines the category encompassing the two boxes as "...world?"
