According to the wiki,
The Tengu built their wall shortly after 1219 AE – http://wiki.guildwars2.com/wiki/Tengu
- 1219 AE was the year of Zhaitan’s awakening – and the great Tsunami which destroyed the original LA, which was the capitol of Kryta. Also, the Tengu gather and found the Dominion of Winds.
- 1230 AE – LA starts being populated once more by corsairs and pirates.
To answer your question, before 1219 the Tengu were all over the world and LA was not the same pirate haven as it is now.
After 1219, the Tengu disappeared from Tyria and Cantha and they founded the Dominion of Winds.
By the time LA was rebuilt, my guess is they had already finished secluding themselves. From that point on, nothing much happened in terms of international relations!
I ran about with them for a long while. They have a permanent green glow is what Khisanth means. You could be able to get the same glow on a sylvari though!
I’m not a MF guru, but I guess it’s the same chance (not profit) – assuming you get lucky with the rares and get an exotic.
Greetings!
Feel free to add me in-game as well!
Three’s a team 
Azione,
In fact, there are many such BAM items. One just needs to know where to look 
Ascended Items:
Certain events and encounters have a chance of dropping “ascended chests”, which allow you to pick an ascended item for yourself. For example, WvW conquests and some World Bosses!
World Bosses:
From some world bosses – you’ll find out which – you can get unique, super pants items. A sick-looking mini? An awesome green-glowing set of shoulderpads? Or a mega cool title? Those are all unique for the boss, mind you! You see people with those very rarely! (I’ve maybe seen 2-3 in total, and they always brag with them!)
The Best Dungeons…
drop the best loot. And since in here loot has the same stats, “best” means baddest-looking. They mentioned above about token armors and weapons – and that’s cool! You also get special trinkets which are worth collecting! An awesome reward is when you get all possible items from dungeons, but that’s way ahead!
But what I mean by “Best Dungeons” is actually one dungeon/path combination:
The Aetherpath. This place is so awesome that you have a chance of getting Nightmare equipment from their chests. But there’s more…
You get to loot a sick set of blue-glowing eerie phantom equipment with unique item names (can’t miss them), each rarer than a legendary. How many people have I seen with those…? Two. Total. Ever. I delve there regularly, so poke me if you’re up for some action!
Fractals:
Last, but not least – the Fractals. The harder you go there, the better the loot. But most importantly, if you go hard enough, you get to hunt for BAM items. Yes, there is a special, impressively mean looking set of Fractal weapons – but they are only for the truly hardcore Fractallers… and if you are good enough, you can try to get your hands on the crown jewel. Not a weapon. Not an armor piece. A special elixir.
And there’s so much more… just go for it.
Want to look mean, and be awesome?
Many ways to do that in our game 
In my dungeon experience, Warriors are still popular for their damage, but a successful, experienced team can consist of just about anyone.
My views as a dungeon leader are that every profession is welcome, as long as it has something unique to bring to the party.
Guardians – Aegis, Condition Removal, Boons, Support (excels)
Warriors – not much besides numbers and a rez
Thief – very useful stealth and interrupt skills (for experienced thieves)
Ranger – an extra party member (the pet), many useful tid-bits, if the ranger is experienced
Engineer – Swiss Army Knife – can do everything, just not that well. Sometimes that’s enough, but not many people can do that, so they play something else instead.
Mesmer – great boon removal, Haste, stealth, portals; in short: the scholar Swiss Army Knife, with less healing
Necromancer – they seem dull and dark, until they get put in a corner, at which point they survive, they put up an army of things, or in general do pretty cool things. I rarely see necros in my teams – always fun to have one!
Elementalist – can put a good dent in people, can help you out in a pinch, and if they’re nifty, they can cause havoc while helping out.
This is all due to the way I do dungeons. Different people will tell you different things; my advice is: get good at one thing, get good at a second one, and you can get good at all of them
But that’s for PvE only!
Fun trivia, GW2 broke down the Holy Trinity of tank/dps/healer!

Such chuckles when I realized!
:D
Not so long ago, guilds used to have a separate chapter (influence, events, and so on) for every Realm they had people on. This got changed and these separate “chapters” got unified into one big guild for all realms, with a common influence pool and guild-wide events.
Your guild should be going through that procedure right now.
Nothing scary
was awesome when we got 15k from our branched chapters!
Cheers!
