5 runes for 5 champions ( deffenders )
So as other threads have already pointed out at the end of ryze's cinematic we see 4 world runes in the demacian vault that much the colours of our in game runes ( runes reforged ) . So lets assume that only 5 world runes exist.( yes i know that the vault ahd more slots..however we dont know if the original purpose of the vault was to hold runes or if some of the runes were depleted and destroyed during the war..).
What if each rune is given by ryze to a champion in order to protect runeterra from a big upcoming void( or targonian ) invasion ? I mean runes can not sit there forever they must serve a purpose within the current narrative and being runeterras ultimate trump card is one such purpose !
so here are some theories about which champions will end up with a rune:
- one rune to each major nation...This scenario makes the msot sense to me since multiple void rifts may open at diffrent places at once. So about the champions that will wield the runes :
-
Domination (red) rune to noxus and its wielder will be

-
Precision ( yellow) rune to ionia wielded by

-
sorcery (blue ) rune either wielded by ryze himself or given to
(shurima) -
inspiration rune to zaun and piltover wielded by
and
( they will put their differences aside to eliminate the obstacle (void) to their common goal : the goood of humanity) Also viktor will have no emotions by then so the world rune wont affect him. -
Resolve rune to freljord wielded by
,
or 
Theory number 2 : All the runes will be wielded by demacians..Well this theory stems from the fact tat demacians may have developted am innate resistance to maigc due to their detachment from it.Also demacian tend to be noble and kind hearted and thus not easily corruptible! so based on that logic we have :
-
sorcery rune to

-
precision to

-
inspiration to

-
resolve to
or 
-
and domination tp
?
And here my theory ( or rather thoughts) ends..i would love to hear everyones opinion on it and even other theories about the futere of the runes ! [katarina-love]
and
from the narrative, and has significant ramifications on the backstories of other champs. The way this is phrased also involves several champions putting aside their differences: Swain and Irelia working together, Viktor and Jayce teaming up, Xerath deciding not to just try and blow up everyone within reach. An idea like this requires so much plot progression and character work that would be a level of advancement in the League Lore that is totally unprecedented.
