So that you can get the heroes there for resources for events with limitations. In order for each hero from the collection to be given certain resources in time (for example, he introduced 1 hero in the guild of 1 star green and Tiba in 12 hours gives 1 grass, introduced all 4 heroes in 1 star give 5 herbs in 12 hours) something like this
