I transmigrated! My host is Garen, and I have all the abilities of a summoner. I've received an epic-level upgrade!
For example, summoner spells: Flash, Ghost, Heal, Ignite...
I transmigrated at just the right moment: the Noxian Empire was invading Ionia. As a member of House Crownguard, a future Might of Demacia, and a close friend of Jarvan, I was bound to take to the battlefield.
This book is ridiculously goofy. The author is goofy, and the story is goofy. The timeline has been changed, with all the League of Legends champions brought together in the same era as the protagonist. I've also added some original ideas to the setting.
As for the central theme, the story revolves around the founding of the "League of Legends." This is a new author's first book, so there may be some logical issues, but I'll do my best to avoid them.
