The Guide (길잡이, Giljahbi; "one who chooses and leads the way") is a special Position that leads the way for the team.
Within the Tower there are two known prominent species with the potential ability to guide. Such species are categorised as the Silver Dwarves and the Red Witches. Silver Dwarves are known for their distinctive silver hair and short stature whilst the Red Witches are known for their bright red hair.
A Guide usually works as a team with a Light Bearer. While the Light Bearer shines light upon the dark surroundings, the Guide may lead its team through the most advantageous route. Generally, the Guide locates the path and conveys the information to the Light Bearer, who then transmit the information to the entire team. However, if the Guide is travelling on a safer path and doesn't need a Light Bearer, then they probably use a Pocket to illuminate the surroundings. Guides, however, have quite low battle capabilities. 
The Po Bidau Family's Research Institute forbids the research of the Guide Position, although the Family Head, Po Bidau Gustang, is fascinated with it. It is believed that he is saving the research for himself.
Guides have excellent analysis skills, and an A-Rank Guide can determine the power of an individual just by looking at them. However, Evan Edrok failed to assess Baam's inherent qualities and thought of him as average. Guides seen so far in the series have displayed an uncommon intuition as to what was going on, most likely due to their ability to read and understand 'paths'.
When Koon Aguero Agnis asks her how she's present on the 29th Floor despite having failed the Floor of Test, Hwa Ryun replies that "I can go anywhere. I'm a Guide, after all", implying that Guides can reach Floors without passing the tests normally necessary to do so. This is further confirmed by SIU stating that Hwa Ryun had technically failed on the Second Floor.
SIU described Guides as a human GPS that can tell the best move or make predictions, but how that comes to be is not known until he further explains it. So even if they predicted that someone would die in a month they cannot give any specific way to avoid it, but they can try their best. Of course, a prediction a day or an hour ahead can be more detailed, someone can't avoid it once you end up on the wrong path.
The most notorious trait of a Guide is the ability of "seeing" the paths of the Tower and instructing someone on the path they can take. However a Guide can only teach the path to those who are capable of walking it. During the events of Headon's Test Evan Edrok didn't help Baam during the Guardian's Test on the 1st Floor because an ordinary person would die if they had tried the solution.
As stated above, Yu Han Sung describes Guides as being able to foresee the future and even change it. Guides are able to find "hidden" things in the Tower and to read one's fate (though not those of Rachel, if not all Irregulars). Moreover, solving complex puzzles and avoiding traps come preternaturally to them. Guides are also capable of seeing their own destiny, they neither fear nor try to avoid their own death, that's how each guide accepts their individual fate.
