Where on Earth is Xacio 555?

[tachyon]

A sentry turret lowers itself from the ceiling. Between it's twin rotary lasers is a single red photoreceptor. It spoke in a monotone but polite manner... for a sentry turret anyway.
"Reception is located in the room to the right. While in Deathwatch HQ do not enter any restricted areas without prior authorization. You may carry weapons but do not draw them. Failure to comply will result in termination. Follow all instructions given. Thank you for choosing Deathwatch."
The turret retracted itself. In the side room their is a desk with a reception droid sitting behind it. Where it not for the fact the very vicious looking Deathwatch logo was painted on the wall it would be no different from any other reception room.
The fembot turned and greeted them with a polite smile.
"Hello and welcome. I am C1-D5, receptionist for Deathwatch Military Contractors. How may I be of service?"

[Ash]

"Hello.Um...Were looking for someone.His name is Xacio.We assume that he is somewhere around here.Can you tell us where exactly he is?",Ash says leaning on the desk.

[tachyon]

The fembot's expression does not change, but the hesitation in her answering Ash's question betrays the fact that it was unexpected.
"... Please wait on moment." she says politely before her face goes blank, most likely conversing on a secure line to some other section of the building.

[Machaeus]

Urufu sighs, glancing around. Three minutes pass. "So...friggin'," he whispers, then half-shouts, "BORED."
"These things take time," a mercenary says.
"I have a negative Patience modifier, okay?"
"A...what?"
"Don't ask," Machaeus says. "Suffice to say he's a Dungeons & Dragons nerd."

[tachyon]

The light returns to the recption droid's faceplate.
"Ah, how interesting. It seems that Kommandant Kit'jhec wants to speak with you personally regarding this matter. I must say that it is not often he will meet clients face-to-face." with a gracefull motion of her arm she indicates to a large doorway down the opposite hallway.
"Through there, and please forgive the environmental systems; you may not find them to your liking."

[Machaeus]

"How so?" Urufu asks. "Are we dealing with a gas lethal to oxygen-breathers?"

[tachyon]

"Oh no, the atmoshpere is quite capable of supporting humans." said C1-D5, shaking her head. "It's just that Denoberians prefer a somewhat warmer climate than what your used to."

[Ash]

"Thanks."

Ash sighs and begins to walk down the hallway the fembot shown them.After a few steps he slows down.

"Bloody hell!Guys.I think I´m melting in here."

[tachyon]

"You ain't felt nothing yet lad," says Gordon, " It's only 353^oK, thats 80^oC or 176^oF, which means he's turned the heat down a bit for us."
The massive 15 ft high doors swung open, and it was like the gates of Hell had been unlocked. Through the heat-haze and acrid, sulphuric air of the chamber, on an enormous command chair sat the Denoberian Ulrask Kit'jhec. His skin was matte black and scaled, contrasted by the shiny blood-red leather vest and urban camoflage pants. His face was every bit as demonic as the rest of him; a large ivory horn protruded from each side of his head and curved forward.
Before the Kommandant where identical 3 figures dressed in black trenchcoats and fedoras. They obviously weren't human; their white faces were gaunt with no mouths or noses. If they had eyes they were hidden by mirrored glasses. One turned silently towards the group, but with a grace of movement that suggested it could have been floating. The group was close enough to hear the tail end of their conversation.
"... it would be in your best interests to do so." said one of the 3 aliens on the right.
"But it would appear that your other guests have arrived, so I shall take my leave." said the left one, who was looking at the group. Strangley, it was in the same voice.
"Untill next time, dear Kommandant." said the the centre most one, also in the same voice.
The trio proceded to move gracefully down and out the door.
Ulrask gave a very toothy grin to the group and beconed for them to approach.
"Welcome." he said in a voice that sounded like rolling thunder. "Please come closer. Don't worry, I only bite if provoked. Now I have been told by my receptionist that you have a very interesting question for me."
((sorry about the length guys Oh, and to get an idea of what Ulrask sounds like, if you've seen 300 he sounds like Xerxes. thats why he speaks in bold font ;D))

[Machaeus]

Urufu nods. "Ash here fought Xacio and wants a rematch," he says bluntly. "Something about insulting his power-armor."
"We were hoping you could tell us where to find him," Machaeus adds.

[tachyon]

The Denoberians booming laugh filled the chamber.
"HA! You fought him and survived? Oh he must like you, yes indeed. I've never known him to miss his mark. Alas, I cannot tell you where he is because I don't know. He stopped working for us many years ago, something of a... conflict of interest."
He sat back and folded his huge arms.
"But I'd be happy to divulge any information that might be handy to you."

[Ash]

"He likes me.Oh yeah.We will see how much he likes me when I am done with him.",Ash mumbles.
"Okay.Weapons,weakness and combat-strategy.Maybe his last known whereabouts.But...before you say anything.
Could you turn down the temperature a bit?
God.It´s so hot in here..."

[Machaeus]

"Dude, for all we know this is cold for him," Machaeus says. "IE, any colder and he'll start dying. I have a protection from heat spell in here somewhere," he mutters, pulling out his spellbook. He casts it and Ash is no longer suffering from the heat.
"I could use it too," Urufu whines. Mach rolls his eyes and uses it on him, then the girls before they open their mouths to complain (his viewpoint, not necessarily the truth).

[tachyon]

Ulrask let out another thunderclap of laughter.
"Your concern touches me, but I am quite capable of survivng the cold you seem to thrive in. I find this simply more comfortable." he laced his finger and leaned forward.
"I first learned of Xacio durring the Khrohaltic Civil War 10 years ago. Ah, now there was a war worth fighting. But yes he was first spotted by my forces durring the Battle of Fyutre Plateau, where he somehow managed to infiltrate the Brotherhood fortress atop the mountain and not only disable their security grid but turn it against the occupants." he smiled, "Most impressive for a child, and especialy, as we thought at the time, a human child. Now this next part you may find interesting. After the battle he was taken away under guard to a secured barracks by what looked to be scientists. I apologise that I cannot be more concise but this information was given to me by my soldiers, I myself didn't meet him until after the war."

[Ash]

"Scientists...Interesting indeed..."
Ash thinks a few seconds about it,but then shakes his head.
"Maybe I shouldn´t think about it too much.Even though I wonder what happened to him..."

"Weaknesses.We already know about the respirator and hot places.
Please tell me that you know one or two more."
