Oh boy it's time for the mega post. This only took a week to write completely and I pray this purges at least some of the space that Arkveld takes up in my brain day to day.
This time, I want to break down its design from more of an evolutionary/biology perspective rather than artistic/symbolic. So I'm gonna put my half finished degree and evolutionary biology fixation to work. This breakdown will be much longer and a bit more speculative than my previous blurbs so bear with me for this one.
As I'd stated in a previous ramble, I theorize that the Arkveld species either existed during an ice age period, or inhabited a very cold region of the planet. Its thick white fur and stony grey skin would (and does) stick out like a sore thumb in most regions, but blends in perfectly with the cold, rocky terrain of the Iceshard Cliffs. Though it shows itself to be highly adaptable, thriving in warm, dry deserts, humid jungles, and boiling hot volcanic caverns. I suspect this ability to withstand extremes comes from whatever intense threats it would have faced in its natural habitat and time period.
Every inch of this creature is both heavily armored, and designed for offense in some capacity. Thick overlapping scale plates cover its neck, back and forearms. These plates appear to move flexibly with the body and do nothing to inhibit its swift, acrobatic movements. Thick, curved, helmet-like horns and jaw plates defend the face and eyes from frontal assault. They can be used to ram opponents or scrape the ground to throw them off balance. The massive horns are held up by its short, muscular neck, which is also well protected from all angles. Though it has very formidable, thick fangs, it is hardly seen using them for anything other than tearing apart already dead prey.
Many wyverns exhibit spikes, hammers, or quills on their tails and Arkveld is no exception, sporting a pointed, triangular scale at its tip. However, similar to its chainblades, its sinewy tail is segmented and capable of extending to jab targets from behind with great accuracy. The tail is also comparatively wide and flat, likely to allow for better steering while airborne to compensate for its extremely small wing membranes.
Getting into some more specific and puzzling features, it's feet and ‘wings’. Why the HECK do these guys have zygodactyl feet??? There are only a handful of animals that have them in real life, and they are all for the purpose of gripping. Owls and osprey have it to catch and hold wriggly prey, parrots utilize it for greater dexterity when holding and manipulating objects, and chameleons use them to grip and climb branches and vines. So why would a largely terrestrial wyvern, armed with 4 immensely powerful prehensile appendages that can toss wyverns like rag dolls, need grippy feet???
And then there's its ‘wings’, which I have a tough time coming up with any feasible explanation for. There's no way this big idiot is able to fly the way it does, and so I'm going to ignore that just a little bit and chalk it up to gameplay purposes for now. These fuzzy wing membranes seem much better suited for short distance controlled gliding, similar to a sugar glider or flying squirrel. Even in its flight animations there is little to no flapping, just a long glide (I know this is used for many other flying monsters as well but bear with me). So for the purpose of this silly speculation I will say these wings are used for gliding rather than long distance or vertical flight!
This led me to putting these two odd features together for a possible theory regarding Arkveld behavior and biology. If we assume it primarily lived in cold, icy climates, perhaps it used those grippy zygodactyl feet in conjunction with the chainblades to climb up slippery surfaces like icy cliffsides. I think it's possible they would have nested on tall, sheltered portions of these cliffs, climbing up the slippery, rocky faces and gliding down to hunt and drive off competitors. We see at the end of the main story, the nest Nata finds is fairly elevated and rocky as well. White scraps of fur are seen around the nest despite the warm, dry climate of the Windward Planes. It is now my headcanon that the Guardian tucked these fur scraps around the nest instinctually, a remnant of its ancestors behavior from a much colder world.
Now once again, we return to the most glaring feature of this beast; the chainblades. For a while I had just sort of accepted that they were a wacky inexplicable feature, and rolled with the rule of cool. But after some closer observations of its in-game model, I think I might have an idea of what these appendages really are. On Arkveld's forelimbs there are three digits, two fingers and a thumb. The two chainblades connect just below the outermost digit on the wrist, overlapping and interlocking with one another when not actively in use. I suspect these chainblades might actually be highly developed, specialized finger digits. Made up of thick, flexible sinews and interlocking ‘shells’, these appendages are prehensile and can all move independently of one another. Surprisingly, the structure is actually fairly similar to that of Rey Dau, which also features two highly specialized wing digits and lacks ‘finger bones’ within its wing membranes. (I might have another crackpot theory about these two species being closely related as they share a surprising number of features).
Speculating about these chains being really evolved fingers does nothing to answer the question of why the hell they can siphon life force on contact. The ability to grapple and restrain other creatures the same size or larger than itself is pretty incredible on its own, and given its incredibly aggressive nature, Arkveld must have had some insane competition in its time. Perhaps that is why it developed this energy siphoning and conversion system, not just for hunting prey but also as a defense mechanism to subdued would-be attackers. In an icy tundra, competition over prey items, space, and shelter would have been fierce, and resources sparse. It could also be possible that it would syphon this energy to supplement for a lack of prey items.
As we see with the Guardian's instinct (or desire) to eat, an Arkveld is not able to sustain itself with absorbed energy alone. In fact this energy conversion is seemingly used exclusively for offensive purposes. Similar to a (average) Deviljho, it uses this converted dragon element in combat with more powerful foes. But again, this does nothing to explain how it can absorb this energy in the first place. And honestly, I cannot think of any good explanation for it. It would be one thing if it was able to channel an existing elemental energy like fire or lightning, or the pure energy source of wylk, and convert it to dragon. But it is capable of siphoning directly from the player in its grab attack, meaning it is not just able to take elemental or wylk energy, it is ALL life energy. Unfortunately there is really no realistic explanation for that, but the dragon element works in mysterious ways and it's cool as hell so whatever.
Unfortunately, one of the most difficult things for me to try and figure out is natural Arkveld behaviors. The ones we see in game are an unfortunately poor baseline, as they are an introduced species that rapidly adapted to live and compete within every environment we see in the Forbidden Lands. There is no good metric to determine how it might have fared among its native fauna, nor do we get to see any interactions between Arkvelds. Because we never see interspecies interactions we can assume that it is largely solitary, and know that a fight would be mutually assured destruction given it's dragon weakness. We see both regular and Guardian Arkveld dominate pretty much every battle it engages in with other monsters. The only real exception being Jin Dahaad, who typically drives the aggressor off with a few hefty ice blasts.
The most obvious thing is that Arkveld is incredibly aggressive, but it's difficult to understand why. Is it territorial? Competing for food resources? Absorbing energy to sustain itself? Just being a massive prick? All or none of the above???? As I'd previously mentioned, to develop as it did Arkveld would have had some incredible competition, and maybe wasn't even the apex predator of it's ecosystem. The development of it's life drain may have been to ease the pressure of that competition, acting almost like a parasite. It drains a host but leaves it alive, then utilizes that stored energy for actual hunts to fulfil other nutritional needs.
I truly hope in future updates we get to see some more unique Arkveld interactions, maybe even something that is able to properly put it in it's place (looking at you Gog and Shagaru). I have so much fun speculating about this particular monster, it has some fascinating blanks to try and fill. This will probably be the last major blob I make about Arkie in particular for a while, but I may do some more musings about my other favorite critters in the future (Rey Dauuuuuu). If you got this far I salute you and thank you for taking the time to read 💙
