Eiol, a world where strength matters but teamwork and planning is also essential. After all unlike other worlds in the vast multiverse, here every person has at least one partner to grow in strength with. Summons, Espers, Guardian or Eidolons. These are the many names that had been used in the past to refer to those partners.
