Onyx Stormpacked a flock into its story , and some readers might have missed the section about the unidentified " sidekick " Xaden refers to being turned into a venin . Theending ofOnyx Stormwas mussy , to say the least , and it terminate on a cliffhanger , lob a few Brobdingnagian questions at lecturer before get along to a end . One of the biggest is that a eccentric , seemingly a major one , hasturned venin inOnyx tempest , whether after being forced or of their own volition , but their identicalness will manifestly not be reveal untilthe fourthEmpyrean Seriesbook . We do know a few things about the mortal who turn , though :

It ’s not much to go on , butit ’s definitely enough to peg down down the list of potential candidate who fit the criteria ; in Sojourner Truth , only a few persona match all the clues : three characters do , in fact . They may not have been one ofOnyx Storm ’s major deaths , but if they did grow venin , it could end up being an even defective fate .

3Brennan Sorrengail

Violet’sOtherSibling

Of the option of characters who fit the verbal description given by the few hints Xaden ’s POV chapter offered , Brennan Sorrengail is a hard option . In the prospect , Xaden consult to the quality as his " new comrade , " and we lie with he means that metaphorically , as he has no siblings - at least , none that he has known : his newly bring out half - siblings do n’t bet . But before he refers to the unknown graphic symbol as his new brother , he uses the countersign " sibling " and he emphasizes it : " The bond between Berwyn and me is one that should never exist , and now that my Sage has anothersiblinghe can use against me … I’m love . "

It could be that Xaden is emphasizing the word of honor " sibling " because he means it sardonically , but when he by and by refers to his new chum , that phrase is n’t italicise . It ’s a pocket-sized clue , butXaden could literally mean a actual sib - just not his . It ’s also worth take note that he says " anothersibling , " considering Berwyn’ssilver - hirsute venin opposite number Theophaniehad already used a Sorrengail sibling , Mira , as a means to trap them . If that ’s the slip , Brennan is the only one who fits the " another sibling " role . He also knewXaden was venin and was trying to cure him , for months . And Xaden would obviously deal enough about his well - being as his own Quaker and as Violet ’s blood brother to examine to relieve him .

2Garrick Tavis

Xaden’s Best Friend Has Disappeared

Another likely prospect who became venin at the end ofOnyx Stormis Xaden ’s remaining best supporter , Garrick Tavis . Like many quality , Garrick has n’t gotten much development in the old Holy Writ but take on a gravid role inOnyx Storm , seeming to maltreat into the void leave by Liam Mairi . When Garrick is poisoned by Faris , Violet , in the narration , describes Garrick as Xaden ’s " best acquaintance . " They ’re clearly close enough that Xaden would hate seeing him go down the same venin course . look at Garrick was one of the few mass trust with the secret that Xaden was turning venin and saw how he struggled , it would also feel like a bit of a heartbreaking betrayal to Xaden , which come through in the shot .

The marked ones in Yarros ' Fourth Wing series did n’t always hold much affection for Violet , but Onyx Storm shows how they ’ve uprise to care for her .

It ’s alsonot clean-cut where Garrick is at the end ofOnyx violent storm . He ’s one of four passenger who are mentioned missing at the end of the book , along with Xaden . That seems notable . Garrick ’s aloofness - exert second signet revealed inOnyx Stormwas tap out , but unless Garrick was stagnant , only something major would have kept him from take back after the fight . twist venin would certainly do that .

It ’s not exonerated why Imogen ’s chapter was let in , but it could be that it ’s just in there to offer a clunky way to make a future let out that Garrick has become venin more dramatic and impactful .

It ’s entirely possible that Imogen ’s POV chapter , which came out of unexpended subject field , was n’t about vote down off Quinnbut about hint that Imogen was finally going to assure Garrick how she palpate about him . It ’s not exonerated why Imogen ’s chapter was include , but it could be that it ’s just in there to offer a gawky agency to make a future reveal that Garrick has become venin more dramatic and impactful . The chapter does n’t really make much mother wit , otherwise - all due respect to Quinn , but she was one of the many side characters who could have been killed off at any time in any mode with zero encroachment on the plot .

1Bodhi Durran

He Never Wanted To Be The Heir Of Tyrrendor

The third and final choice for who turned venin at the end ofOnyx Stormis , of row , Bodhi Durran . survive back to the option of words Xaden uses - " sibling " , " new blood brother " - as Xaden ’s cousin and his lookalike , Bodhi is the closest thing Xaden does have to an actual brother ( again , Xaden ’s raw half - brother do n’t enumerate here ) . It would rend Xaden apart to see Bodhi , of all people , walk the path of the venin . Bodhi becoming venin would also arguably experience most like a treachery to Xaden , specially as he ’d looked to Bodhi to be Tyrrendor ’s successor once he , Xaden , was completely turn to the dark side .

Violet ’s squad has had ridiculous lot in The Empyrean Series , but Onyx Storm has potentially precede the reason why with one hypothesis about Ridoc .

That ’s exactly why Bodhi may have become venin onOnyx Storm , though . He was adamant that he had no desire to replace Xaden as Tyrrendor ’s duke . As he tell Theophanie when she teases him with the crown , " I ’m doing exactly what I ’ve always wanted - protecting my full cousin , my province . " It would n’t be out of the question that Bodhi would change state venin in an attempt to save Xaden , however badly - advised , oreven sacrifice himself in a ill-conceived attempt to leave Xaden with no choice but to contend the urge to in full plow . Whether it ’s Bodhi , Garrick , or Brennan , though , it ’s a shameful ontogenesis that will have a big wallop moving ahead .
