Route and other signs.
Just in case you missed what the gnome said, take "Rue Bird" at the top signpost if you want to continue the normal metal route.
If you want the serious metal route, continue with "xombiekitty".
The rest of the signs are as followed:
Boom and Bust = start of Gas route
SeerQueen = start of Wood route
JillyBean = start of Spice route
