Border Guard

The Border Guard is a non-attackable non-player character who charges the player 10 coins to cross the border between Al Kharid and Lumbridge. They wield steel halberds. They are the only free-to-play NPCs to hold halberds other than the fortress guards at the Black Knights' Fortress.

After completing Prince Ali Rescue they will let the player through their gate for free.

Draynor/Falador


17th September two border guards were added to the Draynor/Falador area. They let you pass for free, and you can't communicate with them.

Trivia
In one of the Postbags from the Hedge, Postie Pete apparently discovered that the two Border Guards were stealing the money. When he further inquired about this, the Border Guards distracted him and were "replaced" with two other guards that look exactly the same.

When you talk to them in the Learning the Ropes tutorial, they will talk about how the residents of Lumbridge are inconsiderate in keeping a dragon as a pet.

In the update of RuneScape HD, the Al Kharid Border Guards received a new look,their old one being a combination of orange and purple.
