Node (WoW)  

A node is a point of interaction. Specifically, a node may refer to a vertex on a graph, like a destination on a flight path map. A node can also refer to a resource node, such as the five found in Arathi Basin. Resource nodes may also refer to the place where herbs and ore spawn. Generally, a node can be any point at which entities spawn, like graveyards or starting locations in battlegrounds.
