a question

There was this instance that we me and a few other people went into that sent waves of level ? enemies at us and then once we died there was boxes with beans. Can anyone give me more info about this?


How do you go there?

What are the beans for?

What happens if you win?

What do all the NPC do that were there?

I ask these questions because I didn't do much there and we all ended up dieing I was told not to talk to any npc and to collect as many beans as possible but the leader disbanded the group. I would really like to do this properly because it seemed like fun.
