So, this is a classic forum game. The typical version goes like this:
Person1: *inserts coin*
Person2: You get a sock! *inserts coin*
Person3: You get a potato! *inserts coin*
and so on. It can be as random as you like. However, since this is the 17th Shard, who cares about regular coins?
*inserts boxing*
and so it begins.
