What does the symbol before the bounty stand for?
It's the symbol of Creation's currency, called Merit.
Are there still undead in the Calameet?
Undead, as in the mindless masses of the great plague do not currently exist. There is more to the Undead topic though.
Do nomadic tribes/people still exist, or are they practically non-existent anymore?
They definitely still exist. Especially in Create's wasteland. Arguably, the Caustic Perch residents are all tribal, due to the lack of an organized society. Sunny Valley has a much nicer climate than Create, and also houses many nomads.
Are there any mutated wildlife that exist outside the domed havens? (examples: Giant Insects like Cockroaches)
There can be. Wildlife is not unaffected by Eclipse Radiation, in whatever form it may come. A wildlife tab will follow eventually. I'll also accept suggestions. If you have an idea for wildlife you'd like to see, then feel free to PM me.
To be more specific (because that's a very broad question) how exactly do the people in Bughouse City become harmonized with nature?
Brondel Island's environment is, despite its human population, basically unaffected. They build their houses, and they have ships, but they don't negatively impact the island at all. They also actively take care of the environment.
Does Brondel Island have a dock/port that people can use to travel on/off the islands...or is the island also isolated from the rest of the world?
It has a side for ships to anchor, although I wouldn't quite describe it as a fully fledged port.
Are Proxies 'tamable' (or, at the very least, able to understand basic commands/requests?)
That would depend on the type of Proxy. The large majority are too massive and/or too dangerous (wether intentionally or inadvertently) for humans to even attempt this. It is certainly possible though.
Because all of the Contact Globes run through a central communications device, does every model have a GPS-signal tracking thing? (Can people be tracked through them, like cell phones?)
That would boil down to your resources. Magna could most likely do that, at least to an extent. Random hacker dude? Not so much.
How exactly does nautical travel work? Are there boats that float on water/air, and if so do they work in any special way? Are there smaller, one-person boats that may or may not go faster than the bigger ships?
Nautical travel is more or less gimmicky, in its purest form. Jubilee uses ships for fishing, as do some other places. Magna has ships, "just in case". Some of the tiny New Pharona islands have ships because the Cerberus Network does not reach them. And some Rogue crews use ships because it lets them stay off the land for prolonged periods of time. Ships, in that sense, are just plain ships, that float in the water. However, Cerberus machines can "swim", as some Cerberus Network roads are barely above sea-level. Ships come in different sizes just as in real life. While Cerberus machines are generally more comparable to futuristic motorcycles, there ARE different versions, some of which are large.
ARE THERE PIRATES?
Rogues ARE pirates Just a different moniker, and not 100% water-bound.
Is it possible to paint a Cerberus--or is that "illegal modification"?
A simple paint job would be completely fine.
Can Calamity Trees be found annnywhere? Or are they mostly just in Calameet?
Literally anywhere. There's even been some that grew in the middle of the ocean. They're named due to being found in Calameet first, but are not exclusive. Perhaps Calameet's environment favors their growth somehow? ;)
Do Eclipse fruits or seeds grant the magical shenanigans? And do the seeds share the same power, or are they different variations of the same "base power"?
The fruits themselves grant proper Eclipse Powers. The seeds can do a variety of things. They can amplify a corresponding fruit's powers. They can grant temporary(!) powers. They can cause great suffering if consumed by someone with an opposing power. They're quite unpredictable.
If one were to eat an Eclipse fruit with multiple seeds, would it be reasonable to assume that their natural potential would increase compared to somebody who just ate a single seed, and/or their powers would be more likely to evolve _____ (quicker? more diversely?)?
That would indeed be reasonable to assume, yes.
Do rogues usually travel alone, or in packs/groups/crews?
Rogues travel in packs, just like pirates. Often times even in quite large groups. Although there are exceptions. The World Devils, for example, are a very small group, with no underlings. The Griselda Bandits, on the other hand, are literally thousands.
Are there "territories" in which certain rogues claim, and are there bases in which these rogues live in?
Seagull Body, along with the general New Pharona network of islands, is largely ruled by the Givennis, a minor noble family, all of which are Rogues. Not officially of course, but practically. Griselda's Lot in Sunny Valley is a large area ruled by Griselda and her crew, and many people consider the entirety of Sunny Valley to be her turf, so to speak.
