A Walk Down Memory Lane I

                                    

                                          
A/N This one's for all the badass overpowered Nico enjoyers!

Opening his eyes, Percy knew he was in a memory, his vision slightly blurred as if he was watching through a fog - probably seeing through the Mist spell that had held the memory back. It was a year and a half after Nico had disappeared, and Percy and a party of Greeks had travelled to Olympus, intent on crashing the council to express their growing concerns. The Gods were staring at them with displeasure while they waited for the final throne to be filled to begin the council. 
"Sorry I'm late," a familiar voice drawled.
 Percy turned around, heart stopping and jaw hanging open as he saw who stood in the entrance to the hall of Gods. Dressed in an immaculate pitch black suit, a waterfall of silk falling over one shoulder akin to the folds of a chlamys, cutting off at the waist where a familiar black soul-sucking sword hung from a silver chain. Nico's eyes slid over the group of assembled demigods, expressionless and cold - if he was surprised at their presence, it didn't show. 
"For someone who can teleport you have a nasty habit of being late, Princey" 
Princey? 
Nico shrugged, dusting himself off, a smirk playing on his lips. "There was traffic." 
The Stoll brothers snorted from somewhere beside Percy. Nico's footsteps were silent as he moved towards their group...and then passed straight by them towards the Gods' thrones. Percy knew his confusion was seeping through his expression. What the Hades was going on? 
Nico bowed before the Olympians, a graceful, practised movement.
"You got your humour from Hades, that is certain." Apollo laughed.
"And his love of dramatic entrances." Nico quipped in response. 
Many of the Gods nodded back respectfully as the son of Hades straightened from his bow. He strolled towards his father's empty throne and Percy expected him to sit on the ascending steps as he once had at the end of the Titan War. But Nico seemed to have a death wish since perched himself on one of the throne's armrests
Percy wasn't the only one outright gaping. Was Nico trying to get himself smote?
But no lightning came, in fact most of the Gods didn't even bat an eye, Hermes was grinning at the demigod's reactions.
 "Shall we begin?" Nico said in that same bored drawl.
 "I, Zeus, King of the Gods, call this meeting of the council to order." Zeus boomed, "The first item on the agenda, our demigod guests who saw it fit to intrude on our meeting." 
Percy winced, stepping forwards. "Umm sorry for intruding, but we've been worried that something is brewing. For almost a year now we've not had any monsters try to attack either camp. And when I was travelling this week, most of the monsters we saw outright ignored us, despite my being a child of The Big Three, and being hated by pretty much all monsters'' 
Percy paused his speech, noticing none of the Gods gazes were on him anymore, they were all looking at Nico, who remained impassive. When the son of Hades finally noticed their stares he arched a bow as if he wanted to say 'Seriously?! Why me?!' but instead he nodded formally to the Gods before turning his gaze to Percy and the Greek demigods. 
"It's true that monsters are roaming in packs and with little interest in demigods outside of the Camps. It is our belief that they are searching for something under the orders of a minor God, Titan or Primordial." 
"I'm sorry, but what is he doing here? Why does no one seem to care that a Hades spawn is waltzing around like he owns the place, I mean the freak is trying to speak for the Gods." An Ares kid raised his voice from the crowd.
