You may assume that, at least in this directional realm, Ra'bin is your guide and will be someone you can call on when you're in that area or having trouble. This will be especially true if Ra'bin rescues you from any difficulties. It might even be true that Ra'bin is one of your guides, period. Meaning you can call on him no matter where you are. The best way to find out is ask.
Birds tend to be frequent guides in the East.
Snakes in the South. Bears in the West. And Wolves in the North. These aren't hard and fast rules, just something that a lot of journeyers agree on. And if you keep a journal you will be able to notice things that pop up regularly.
