"Welcome to Mount Justice," Aquaman said, as he and Element arrived through the portal that was used to enter the base.  Aquaman showed Element from the portal reception chamber and into the base at large.  Around them was an open living space complete with all the necessary home furnishings.  "I'm sure you recognize Robin."

Sitting on a comfortable, fashionable couch sat the famous side-kick to Bat-Man.  He waved.

Lemuel's eyes were wide as he was escorted in.  He still wasn't used to his powers or his new name.  "Of course I do," was all Lem could manage to say, when Aquaman introduced him to Robin.  He waved back, wondering if he would actually get to talk to him now, or if the tour was to immediately continue.

Across the room a group of shadows coalesced together and rose from the floor, forming into the hero known as Raven.  Element remembered that besides himself, she was the only other non-sidekick on the team.  He also remembered that they had both been candidates for the Justice League prior to the formation of Young Justice; she was still pretty bitter about it last he checked.

"I think you've met Raven," Aquaman said.  Raven didn't say anything, she only stared.  Element also remembered that Raven was a moody, mystic.

"Uh, yes, yes of course." Lem replied.  "Good to see you again Raven." Lem said, trying to keep it low key.  "It's been a little while.  Glad to see  you're still in the game.  I look forward to working with you."

Raven smiled slightly at Element, which, for Raven, was actually probably a big deal.  Before she could respond verbally, however, a figure swooped down from up in the incredibly high ceiling (Element just now noticed that the cave-ceiling did, in fact, reach very high and was filled with stalactites).

"What's with all of the gloomy greetings?" said Hawkgirl and she landed in front of Element and heartily shook his hand.  Element remembered that Hawkgirl was from the warrior race of aliens known as Thanagarian.  There was little contact with their distant race so not much was known about them.

Her older, Justice League counter-part, Hawkman, wasn't a real Thanagarian he'd just absorbed the memories of a past Thanagarian who'd landed on Earth during the Egyptian era and used the Thanagarian wing harness to fly.

Hawkgirl also had a Thanagarian wing harness which allowed her flight, and carried a mace made of Nth Metal (a mysterious substance with various mystical properties).

The outgoing greeting perked Lemuel up a bit.  He smiled back at Hawkgirl and shook her hand back.  "Nice to meet a Thanagarian," he added.

"Hey the new kid!" said another voice.  From the back of the room a red suited figure strutted forward.  Element recognized him as Green Arrow's sidekick (not that he'd appreciate that term) Speedy.    "How are you?"

Speedy extended his hand.

"A little overwhelmed at the moment," Lemuel answered as he took the proffered hand.  "But I still prefer not to be called kid."

"I know what you mean," Speedy said, winking.  Aquaman put his arm around Element and led him past the others.

"This is the common room," Aquaman said motioning to indicate the room.  "Each of you has a room further back.  If you go through this way," Aquaman led Element through an opening in the rock wall, "you enter the dock."

The submarine dock was a quite spacious chamber with a high, cave ceiling.  It also housed a control room for dock.  There were no subs docked, at the moment, however.  Aquaman seemed hesitant to leave for the next room.

"This is the training room," Aquaman explained.  "Solid light holograms allow for real-life simulation.  However, blocks have been put into place to prevent injury."
