Fort Trident / Villain Counter-part
Fort Trident looks like the inside of a typical Longbow base (One where you enter via submarine), limited to the first two rooms. The main difference is that all of the TF-related signature heroes are around, with SG portal-looking portals that link to the zones where their TFs actually kick off from. Plus, the Longbow staff is hard at work instead of standing around waiting to be attacked. I'm not sure that it's worth taking and posting screenshots of, but for your sake I hope someone will disagree!
I know Fort Trident is in the Lake in Atlas Park, but where's the villain base?
The Crucible looks like Tyrant's old lair at the end of the old Praetorian arc, except all the patrons and an arbiter are your SF go to guys. The place is littered with random thugs and Arachnos guards, while the thugs are being made to do embarrassing acts for the Patron's amusement.
Funny thing about the Crucible, though, is there's an NPC standing around with the title of "Arachnos Loyalist." He looks like a combination of an Arachnos wolf spider and a Crey soldier, especially with the backpack he's carrying. What's up with that?
To see Fort Trident, make a new Hero, go to Atlas Park, find the marker on your map, and go inside to see.
To see The Crucible, make a new Stalker, go to Cap, find the marker on your map, and go inside to see.
Simple.

Biggest Troll on the forums? I'll give you a hint:

Can anyone show me the insides of these two special places for heroes and villains? I think its like the Citadel red-side, I dunno.
Please and thank you.
