Man I love using Sveta's beastform, punch enemies to death! So yes, very over powered sometimes, but if the beastmen are not the most powerful, then whom?
Prox. If they changed along with the Golden Sun they may have become an entirely new race (like a dragon humanoid perhaps since they are mars affiliated.) Also, I'm not quite sure but wasn't it said or theorized that it was the Prox people who helped in the sealing of the four elements?
I feel like I remember hearing that Prox was partially to blame for the reason they even sealed them away in the first place. Although they came back to save Weyard, could they have evolved into something more post-the lost age?
I fer sure want to see moar of Prox.
As for the wise one, I still look at him as a kind of ward, but he is the stone of sages and a philosopher stone afterall....
and I really want to know what the machine in Konpa ruins was doing.
Why house something like that in a ruins that was once made of pure gold?
I didn't much like Sveta's beastform, it felt like I was cheating at an already terribly easy game. Looked awesome though.
Yeah, that's something I would like clarified proxians having a dragon form or not. Because, we've never seen one transform by means other than fusion, or (IMO) possibly outside influences (Wise one), with Karst & Agatio.
But, my reason for saying they aren't the most powerful is because we don't know what's out in the reborn Weyard. There may be races that just popped up in a similar manner to beastmen.
The Wise One. He really gets me thinking. His description in DD's Encyclopedia says he was "forged" and "is now known to be what the ancients called a philosopher's stone" That right there says a lot, and nothing at the same time.
Philosopher's stone in definition (in actual alchemy) mirrors that of Kradens description of the Stone of Sages. "The wisdom stone...the Stone of Sages. This stone dominates everything. It can transmute crude matter into gold, even thwart death itself" -Kraden
So, I believe you're right on the nose about that. Some may disagree, but I find it plausible.
The interesting part, Kraden said the stone of sages forms when the golden sun forms. So the question is, is there another "philosopher's stone" out there with the formation of the golden sun? Perhaps, Alex, is, in a way one?
Answering your questions with questions seems counter productive.

I could theorize on the Tuaparangs machine but, it'd have no basis what so ever. So, I won't for now.
The Konpa Ruins I've had a gut feeling about it ever since I ran into that place on dd, that something more is/was there.
You posting about The Wise One & Konpa made me think of something.
The Wise One in theory (if it is a philosopher's stone/stone of sages) can transmute crude matter to gold....Like, say, maybe, Konpa Ruins?
Maybe it awakens the temple for it's true purpose.
The ruins were once gold, but we did not see such in DD.
"The once-glittering Konpa Ruins: These stone ruins are thought to have been a spectacular temple covered in gold. It's ancient nature is still under study, but scholars believe its gold was the ultimate symbol of alchemy"-bookcase at Carver's camp
"Within this place we celebrate the gift of psynergy and pay homage to the natural world for it's rich bounty."-Pillar in Konpa Ruins
"The glorious power held within these hallowed halls will be released again, when the world once more has need of it"-Pillar in Konpa Ruins

Could be talking about the glyph book, but not sure.
Also, the encyclopedia entry states it was a hub for ancient adepts to share ideas with visitors. So it had some sort of importance in the past.
What does it all mean?
I dunno, haven't gotten that far yet...I have my strong suspicions though.
Apparently, if you mention Konpa to me I go into a lengthy tangent about it.
