Talk to the concerned peasant and he will tell you that the town is crumbling and will ask if you can repair it, and will give you a key, have no Zamorakian items equipped or when entering you will be hit a 20 and a message will appear "It's blessed, you seem to realize when you feel drained". Enter the city and peasants will come out of there houses and begin to follow you asking things like "My foot all achy, can you kiss it better?", "Free stuff please!" and "My Zezima is sick!" (obvious reference to Zezima)
