The reason transformations aren't  reversible is once you hit a certain amoount of fleshwarping on the same person, they "harden" like the  body growing scar  tissue.   After a point you can't  change further, and trying to sculpt flesh like clay becomes harder after a change, rather akin to firing a clay pot in a kiln. 

You can change them again, but pushing them back to their original configuration is akin to trying to un-fire a clay pot, and removes the danger of the principal  antagonists of the setting.

The best most can hope for is whoever changes them again has a delicate enough touch to prise out a mana seal and resculpt them into something more able to live a normal life, even if their original human form is lost.

Only demons and half--demons retain any ability to sculpt themselves at will.

However unlike clay, the flesh is supposed to be flexible which can changed and therefore reversed back at any time though which I somewhat disagree with this.

Although unfortunately this is how Demon Man designed the world otherwise because he wanted a world where reversable transformations are 'hard to achieve' and this is his in universe 'explanation' or justification when he wrote the world just like how he made principal antagonists are 'unbeatable' and high powerful for this very purpose.

However though, it is still 'depression' and 'nihilistic' that things will never remain the same pre-transformed though which is one of the biggest reasons why I don't like permanent transformations of Beliali universe.

You know I always toyed the idea about a scenario where everyone in Assiah are transformed and there are no normal humans left  since I've created a thread about this way back that nobody responded to though since realistically if transformations are highly contagious and happens in a ever increasing rapid rate, then realistically all of humans would be transformed into sex creatures in that particular world mathematically of course.

Of course though that's also why it's almost like your character has to be made out of metal/wood/rock/etc or any type golem/robot just to 'survive' in the world of beliali without the fear of being inevitably transformed. Unless one was immune to transformations of course which maybe mana/dcum/etc has entirely different effects on them...

I don't see why that should be a problem outside the Belial universe, but the rules of the Belial universe are already established. Maybe one could come up with an elixir that made a person way more plastic (and probably unstable) than usual for a limited amount of time, like an hour or so. Within this period of time the body did not harden in a specific form, but could continue to try different forms even if going back would be difficult (prehistoric fishes could evolve into early amphibians, but amphibians have never returned to being fishes again). Transformations are about moving forward, not going back. Once the time is out, the form you have at that moment becomes permanent.

However there is some flaws in this argument. that if this is the case, then our very human forms should be 'permanent' as well.

Also I would disagree on your statement about Transformation which the genre's meaning is rather subjective which to me, it means "Trying out different forms and feeling the sensations of transforming into that form"

Also I heard that Vicissitude alterations from VtM even the most extreme ones are more likely reversible but yet Beliali's somehow isn't....

Of course though maybe our world (or the WoD) and Beliali work in different laws and worlds though.

Uh....where to start?

First off. I have no problem with general discussions of ideas. That's what this place is for. In fact, I encourage it. I do not even have problems with non-canon Belial stories or stories that would not fit within Belial's canon. That's what the Expanded Universe section is for. There is also the Transformation Stories section for all kind of non-Belial stories, which are welcome, too. Its not like only Belial-related things are allowed in this forum.

I'd just personally prefer for non-Belial stories or non-canon Belial stories to be marked as such or posted in the appropriate section of the forum but that's just me being a bit anal about these things.

In regards to changing the canon of Belial. That's obviously up to me and won't happen. I made transformations permanent by usual default for a reason. Without it, if they became interchangeable as clothing, they'd lose their impact and the whole universe would fall apart. At least in the form I envisioned it. That doesn't mean that temporary transformations, as Finaro describes, are impossible. Just rare or only possible under specific conditions, e.g. a demon can change a person back and forth however they want, demons themselves are shapeshifters anyway and so are some half-demons. Powerful mages might be able to do the same to some extent or at least change their own bodies as they please. There might be a very specific machine or alchemical solutions to change a person back to their original form if used to transform them in the first place. However such a device or substance would need constant control and would be very rare and/or expensive. If there is a good explanation for it, I have no problem with such things in the canon itself, so long they are not aimed to overtake it and change Belial as a whole (in which case it would belong into the Expanded Universe).

Nonethless, as mentioned. Finaro is free to discuss his ideas and everybody is free to join in. I wouldn't add it to the canon of Belial but it has the right to exist as an alternative.

In regards to the proportion of transformees in the general population:
Nikita is absolutely right. The obvious focus of art and stories on transformations distort the picture. Transformees make up a very small percentage of the overall (imperial) population (with exceptions like Jizza and Suto). I'd compare them to extreme bodymodders or physically disabled people (e.g. wheelchair users), where despite not being uncommon, they still stand out to some extent.

Furthermore, the reproduction question was brought up. Most transformations do not affect the dna or at least reproductive cells. As such, most transformees have normal, human children. There are some exceptions, either accidental or by design. For example, Freyan women give birth to normal babies. That's why there is a ritual of transformation when their daughters turn old enough. People affected by the B-virus on the either hand, find their reproductive organs changed on a genetic level, so they can only have offspring with hybrids of the same animal species and give birth to hybrids themselves.

I am glad that it's  permanent  I think it's more of an impact. I kind of prefer them to try to get on with their lives afterwards as best they can. I do believe most transformees try to cope and adapt to thier new forms and are happy. Most not all I am sure there are plenty that don't like them. However I am sure they come around eventually.

!@Finaro

Its okay if you would like to write stories with non-permanent transformations, its what works for you. I also think people have been very open and welcoming to your tastes, but I think you would have to see that a lot of the people on the board don’t have the same tastes as you do. I’m not saying your tastes or ours are right or wrong, but calling the main Belial cannon “problematic” comes across a little condescending to those who do like those types of transformation.

I think if you have some ideas for temporary TF stories, I say go ahead and write them, but trying to talk people into liking your kinks is a bit of an uphill battle.
