Most of the waters that Rubble Spring possesses originates from the body of water known as Topple Lake, where a waterfall falls down into the area, creating the rivers and streams that the community can see in the Frontier.

There are four notable landmarks that can be found in the Frontier:
- Collectus' Hole, previously referred as the Death Portal, is a portal service that enables the players to quickly be teleported to the pillar that Collectus stands on in Greenhorn Grove. It is located further inland, near Greenhorn Grove. This area is marked with a skull sign, hence why it is dubbed as the Death Portal.
