Security Guard

 The Security Guard is an random event. If a player has their recovery questions set, the guard gives them a security book, another reward, and recommendation to come to theStronghold of Security.

Since the Random event update the Security Guard travels around random places, such as the Grand Exchange, and hands out free security books to anyone talking to him. He will teleport to other places a few minutes after being talked to. When he leaves, he will say, "Well, I best be off!", or "Ah, time I was off now, bye!"

If players spoke to him he gave players a security book and any of the following rewards:
 * 20, 40, 80, 160, 320, or 640 coins
 * Uncut gems (sapphires, emeralds, rubies, or diamonds)
 * Half key (members only)
 * Cosmic talisman (members only)
 * Spinach roll
 * Kebab
 * Nothing
