Road Building

allows your character to construct Milestones:

uild &gt; onstruction &gt; Miestone

Once you have an initial milestone constructed, you can build mini milestones by right clicking the initial milestone. Continue right clicking the new milestones to create more. Link them, and you have a path-findable road.

In-Game Text
"Roads go ever ever on,

Over rock and under tree,

By caves where never sun has shone,

By streams that never find the sea;"

Road Building allows you to construct milestone objects that you or another Hearthling can then follow.
