ok buckle up kiddos it’s conspiracy™ time: due to the consistent use of the dative case throughout the raven cycle gansey can be considered a raven king in the series, directly paralleling owain glyndwr. in this essay we will (actually give you an essay i said buckle up)

According to the great source of knowledge that is wikipedia, Glendower used to serve in King Richard’s army (in August 1385, but that’s not really relevant to this).

Because I know so much about Latin (this is a bold faced lie I know nothing about Latin so the following is credited to Dan @josephkavinskys).

Dan speaks here hi henlo (just for the record I verified all of this with my Latin teacher (who has a degree) so dont @ me if it’s wrong I’m trying my best):

“Rex Corvus, parate Regi Corvo”, which has been translated to ‘make way for the Raven King’ could instead be ‘King Raven, prepare for the Raven King’, or even ‘The King Raven is preparing for the Raven King”. The Latin ending ī is reserved for second declension* plurals and dative cases** so it is saying “for the Raven king” when it says “Regi Corvo”. but “parate” (prepare the, or in this case, prepare for the) is not necessarily dative which means it is also able to be part of the subject, “Rex Corvus”. Latin also does not require definite articles like “a” and “the”  — therefore, ‘Raven King, make way for the raven king’.

In that case then: was Glendower making way for Gansey aka Glendower was supposed to serve Richard Gansey aka King Richard? Did Maggie name him Richard because of this? And what if those birds were telling Glendower to make way for Gansey? Did Glendower make way for Gansey by dying?

Not only that, but the Latin grammar of “Rex Corvus, parate Regi Corvo” is actually not completely correct. The correct dative form of rex is regi, and corvus would be corvo. This is a common mistake with young Latin students according to my Latin teacher, which would lead me to believe that it could feasibly be made by Ronan because according to Jenna he is “just a Latin student who really just speaks tree” and that’s valid, which leads us to this: Could Ronan be the one who dreamed the signs of Glendower, likely to satisfy Gansey, just like he dreamed Cabeswater? MAYBE SO.

Also worth noting that while Adam and Gansey’s translation of this is written, it is not read, it is spoken. This means that while the comma is written, it may not be officially “there” due to the relatively unreliable POV of a bunch of high schoolers.

Also, there is a consistent theme of parallelism throughout the series, with repeating motifs like the hubcap in the lake by Cabeswater and Cabeswater’s strange flux on time. It makes perfect sense to us that Maggie would do her research and throw in this little easter egg, along with all the other symbolism behind Gansey’s being Glendower throughout the series.

*(Latin words whose nominative singular noun form ends in -us, i.e. corvus) 
**(A specific conjugation of a Latin noun that indicates an indirect object, or giving something to/doing something for someone)  

tl;dr: Glendower had to die to make way for Gansey to live and therefore Gansey is the Raven King.
