This monster has been known as The Keeper ever since the First Masters put him in charge of all their Books. He lives to defend the Library and all the precious wisdom held inside it. If anyone knows the history of Monster Legends, it’s The Keeper.

Some of the rewards for collecting chapters of the books include The Keeper's Cells, and as soon as you get enough of them you can craft The Keeper in the Lab.

So make sure you collect and hatch as many Monster as you can to get him and many other wonderful rewards!
