What is the mystery to the hall of heros in Neopets?

Answer 1

this is a plot. a plot is a game that is not obvious (obvious meaning: doesnt have a giant 'play' button) . it is completed by clicking on a sieries of buttons all over neopets. this one mostly takes place in altador. some of the buttons will not be there until you press another button. some you might not even know existed. after you do everything, you get a grand prize of about 4500np, and a few neat trophies. then you can go back every day and get another smaller prize. here is a guide:http://www.jellyneo.net/content/plot/index.php
