But instead of crossing over, He is transmigrated 300 years into the future, to an alternate reality.One where Summoning Families ruled the world with iron fists and magical contracts. Here, power was measured by the magnificence of one's first summon.Now as Altair Elfender, an eighteen year old disgrace to the proud Elfender family. A late bloomer whose summoning seal appeared a full eight years after his coming-of-age ceremony.When he finally summons, he summons a dusty old book.Disgraced and labeled a failure, Altair is ridiculed for calling forth the “peak of uselessness”.But this is no ordinary book, the tome is a timeless Grimoire of Fallen Legends, containing the contract spells of all heroes from past, present, and future.Now, they answer to one summoner.And as the world prepares for the Summoner's war, Altair rises as an anomaly,the only summoner whose power does not lie in dragons, beasts or spirits……but in heroes of legendNB:-MC gets strong fast-Tons of interesting heroes to summon (if you have a favorite you'd like to see, drop them in the comment section)-Sit tight for the Summoners War-Progressive fantasy-Violent scenes-Harem
