I recruited many hero’s but don’t see them anywhere, where are they.?

All of you heroes can be seen by taping the hero menu icon at the bottom.

Remember that when you recruit in Noah's Tavern you get hero fragments. Sometimes you get 10 but usually you get only 1. You need to have a minimum of 10 for a hero to recruit them so you may have received some fragments but not got enough to recruit yet.

In the hero menu you can tap in the 'Not obtained' tab to see all the heroes and it will show if you have some fragments for them so far.
