The runes of Lífþrasir
Lífþrasir (リーヴスラシル Halkeginian: ᛚᛁᚠᛞᚱᚨᛊᛁᚱ, "love of life") is the fourth familiar of the Void. It is also known as the Heart of God (神の心臓).[1]
Powers and Abilities[]
Lífþrasir can increase the magical power of a void mage spell. However, to use this power shortens their life force and using it with no control would kill the Lífþrasir.
Put simply, Lífþrasir serves as not a catalyst for spells, but amplifies them using the familiar's life force as fuel. However, that is only half of its power and the gentlest. Its other half is the power to stockpile magic spells, make them stronger, and effectively turn themselves into a living bomb.
Saito became Lífþrasir when Tiffania summoned him as her familiar.[2]
Known Lífþrasir[]
Trivia[]
The runes read "Lifdrasir" (ᛚᛁᚠᛞᚱᚨᛊᛁᚱ) as opposed to the correct spelling of Lífþrasir, which is "ᛚᛁᚠᚦᚱᚨᛊᛁᚱ".
Etymology[]
Lífþrasir is named after Lífþrasir from Norse mythology, one of two humans who will survive Ragnarök.
