A Flag is a gravestone that can be bought from Father Aereck in Lumbridge church after completing The Restless Ghost. It is the second cheapest gravestone available and the only gravestone with an animation. It is sometimes favoured by non-members because of its unique appearance among the other gravestones available. It is one of four gravestones a non-member may buy.
During the 2011 Hallowe'en event, an advertised Flag read "Give in to the ultimate surrender with this little white flag!"
