Forseti 

A ridiculously overpowered wind magic in Fire Emblem: Genealogy of the Holy War and Fire: Emblem Thracia 776 that makes the player capable of soloing most chapters with the wielder of the tome, direct descendants of Forseti are the only people capable of wielding this holy tome..... or are they. Wielders before *spoiler alert* Sigurd dies, along with most of his army, is only Lewyn for Chapters 4 and 5. POSSIBLE wielders after Sigurd and his army dies are Arthur, Ced, and Cra... I mean Corple, wait it might rot in the dust if Lewyn is a virgin. In Thracia 776, the only wielder is Ced.

Fire Emblem: Awakening being heavily nerfed as it only does less than half the damage and the tome grants only 5 extra speed making it significantly worse than the original appearance, on the up side, anyone with the tome ranking of A can wield it.

Turn 12: Ced in the middle of the field wielding Forseti, with 15 enemy mage knights in range of attacking Ced.
Turn 13: Ced in the middle of the field still wielding Forseti, no enemy mage knight remains.
Player: "Good god, Lolsety is so OP, this tome is even less balanced than League of Legends.

Forserious

A colloquial term first heard in the backstreets of the small northern Australian township of Gordonvale. Usually used when you are surprised by something you are told and want to confirm you heard correctly.

Renae said to Kym & Ben "Are you forserious that you competed in the worm grunting competition in only 1 squetre?"
