Sadly , the follow twoEmpyrean Seriesbooksdidn’t quite attain the peak of the first one . And there were some notableproblems withOnyx Storm , as fun as it was to read .

WhileOnyx Stormboasts many of the strengths of its predecessors — from snarky dialogue to shocking wrench — it assay to expand the series ' world in ways that do n’t always benefit the book . Perhaps this will pay off in thenextEmpyrean Seriessequel , but as its own entity , Onyx Stormhas a figure of shortcoming that mirror those of the MCU Phase 4 .

The MCU Phase 4 Was Criticized For Being Too Messy & Not Cohesive

There Are Too Many Characters, Storylines, & World-Building Additions In Onyx Storm

Like the MCU Phase 4,Onyx Stormfeels a bit unwieldy at times , as the Christian Bible introduces new worldly concern - build up elements , attempts to flesh out more supporting characters , and mix a lot of different plot line . The various plotlines often feel wind at times , with theFourth Wingsequel only getting to the meat of the story during the last third of the tale . Before that , Violet and her friends spend much of their time seeking outAndarna ’s seventh strain of dragonand Xaden ’s venin curative . And the result of these commission are pretty underwhelming , at least in this book .

Onyx Storm ’s messy plotting create some plot hole and continuity inconsistencies , but one conversation wreck its entire scoundrel premise .

This feel standardised to the MCU Phase 4 , which attempts to start afresh on the dog ofAvengers : Infinity WarandAvengers : Endgame . alas , this chapter of the dealership go to match what came before , mostly because it introduce too many plot line and heroes and just offer any payoff . Four years afterShang - Chi and the Legend of the Ten Rings , viewers are still waiting to see Simu Liu ’s hero in a sequel , especially after the movie ’s post - credits prickteaser . And the event of projects likeEternalsandMoon Knightare barely mentioned again .

The trips to the various Isle Kingdoms start to experience insistent , andOnyx violent storm ’s endingthrowsa lotat readers in just 100 or so Page . Additionally , the novel supply so much populace - construction that ’s hardly touched on before , from all thenew detail about the veninto the fact thatFourth Wing ’s godsare real and involved in human matters . Together , all this starts to feel mussy .

Onyx Storm Felt Like All Setup For Another Story

It Builds Excitement In The Same Frustrating Way As The MCU

Onyx Storm ’s meandering storylines are n’t the only thing it has in common with the MCU Phase 4.The thirdEmpyreanbook also sense primarily like setup for succeeding installments , which is true of many of the picture and shows from Phase 4 . While each of them has their own narrative , the MCU ’s Phase 4 project always drop the concept of bigger threats , new characters , and future team - ups in front of viewers . The worst part is , many of these tease do n’t actually tear apart out , likeWandaVision ’s White Vision or the introduction of Kit Harington ’s Black Knight .

This backfires , as it ’s difficult to look forward to a team - up or get empower in the continued story when the character are n’t fleshed out well .

Yarros ' world - building continues to expand from novel to novel , and there are several side part who are re-introduce throughout Onyx Storm .

AndOnyx Stormalso introduces new subplots with supporting fictitious character no one is really invested in . Even an unlikeable newcomer like Halden gets his own frustrating plot line , and antecedently underutilized role player like Lewellen are given a middling moment of attention . lamentably , this come at the expense of page time for established characters lector already do it . Rhiannon and Sawyer feel sidelined throughoutOnyx Storm , and even character like Imogen and Bodhi do n’t get the care they deserve , especially given their importance to the story .
