Guard

There are many guards in RuneScape, usually in populated, major cities, such as Falador, Varrock, Ardoughne, and others. Their level ranges from 20-30, and they are quite weak and pose as a bit of a nuisance, especially if you are a member trying to steal from stalls, at which point they intercept you in the theft, and then proceeds to attack you, thus preventing you from stealing any more until combat is over.
