As Oz walked the night-time London streets he kept himself cloaked and concealed. After a while of walking he found a big enough secluded area for him to transform and start his journey. Just to be safe, Oz put up a couple of wards in the area as well just to make sure nobody would see him.
{Okay Norberta, you can come out now}
After hearing this command, Norberta hop out of Oz's pocket in glee and flew around Oz's face before perching herself on his shoulder.
{What are you doing now papa?}
Looking at the little dragon Oz smiled.
{You may want to stand back a bit norberta}
Norberta hearing Oz's command immediately flew off his shoulder and landed just a bit further away from Oz. An inquisitive look filled the little dragons eyes as it watched Oz's every movement trying to understand what he was going to do. Oz closed his eyes as he commanded his body to transform into his Animagus form.
Soon the human boy that stood there vanished in front of Norberta's eyes and was replaced with a black dragon with striking purple eyes. The size of Oz's Animagus form was pretty big as well, however in recent training sessions Oz had managed to learn how to limit his size to a reasonable level compared to when he first went through the Animagus ritual. Norberta looked at Oz in his dragon form in shock but also glee.
{WAAAA, Papa is this your true look?!}
Oz lowered his head towards the little dragon and ushered her to get on. Norberta immediately responded to the command jumping onto Oz's head and holding on tight.
{We got a bit of a journey ahead of us Norberta so be prepared}
Throughout all of this Oz stayed cloaked and also kept Norberta cloaked as well. Realistically however in this form he didn't need to cloak himself as the night sky would act as a natural camouflage however it was better to be safe than sorry. Oz also heaved a sigh of relief as he managed to block the trace from realising he had transformed.
Soaring into the skies Oz looked down upon the London metropolis and looking at the stunning view his heart skipped a few beats. He had come so far in these past years and now he was at a stage where he could soar into the heavens. His heart raced with excitement thinking about where he could go from here.
After a while of taking in the scenery, Oz finally started to fly off in the direction of his destination, towards Stonehenge.
.
The flight towards Stonehenge was pretty smooth for Oz as he barrelled across England's skyline. To keep himself from being bored he'd talk to Norberta, the latter of whom was still perched on his head enjoying the ride herself.
After several hours of high speed flying Oz noticed that the area below him was where he needed to land.
{We're here Norberta}
Oz notified the small dragon on his head that they had finally arrived waking her up. Oz then started his descent down into a field as dawn was breaking. he looked around to make sure there were no people and even used his dragon eyes to be doubly sure, after a long check he realised the coast was clear.
Finally, Oz landed in a field and on the horizon he could see the rock formation that made up Stonehenge. As he landed Norberta flew off his head as Oz transformed back into his human form. Seeing that her 'papa' had transformed back, Norberta flew and landed on Oz's shoulder as Oz started to walk towards Stonehenge.
'So im finally here... Let's hope this will serve as a good base for me in the future'.
Oz took a slow pace as he walked towards the historical site. As he walked towards his destination he recalled some history about Merlin in his previous world. It was said in history that Merlin moved Stonehenge from Ireland to this location in England as a memorial for the hundreds of Britons treacherously slain by the Saxons. Seeing as though Merlin definitely existed in this world, Oz wondered if he had actually moved this site previously if such a story was true. If so, Merlin's magic must have been on another level to move his base of operations if it was so an entire country across.
As Oz allowed a myriad of theories to flow into his head, he eventually arrived at the ancient rock formation. Initially, he couldn't sense anything magical from the area at all however he half expected this considering how meticulous Merlin was. Just to be safe before he investigated, Oz se up a ward around Stonehenge itself as he started to look into what was needed to enter here.
'Merlin would make the key for the entrance something exclusive to his bloodline... So my blood itself is probably the key much like how the Ambrosius ring responded back at Gringotts all that while ago. Question is, where do I drop my blood?'.
Just as Oz was questioning where he would have to drop his blood to activate this base, He noticed something in the middle of the monument with his dragon eyes. To a normal wizard, they would have missed this however Oz could faintly sense a tiny bit of magic at the rock place in the middle of Stonehenge's formation. Walking over to it Oz could see a small hole, almost pin-sized that led into the rock. His instincts told him that this was the 'keyhole'.
'Whelp, lets give this a go'.
As Oz was investigating Stonehenge, Norberta was flying around wildly enjoying her time outside. Sensing her 'Papa' had found what he needed though, she immediately flew back onto his shoulder and looked down into the little hole in the rock.
{Papa, I can feel there's something down there...}
Hearing this confirmed Oz's suspicions. He noticed recently that Norberta's magic sense was much more powerful compared to him probably because he was a 'half-dragon' while she was a born dragon. Oz took out a little knife as he pricked his finger letting blood flow. He dropped his blood into the small hole and as the blood dripped in, the area around him seemed to come to life.
Oz's ward was immediately destroyed and replaced with a stronger ward, one that was leagues above his own. The stones that made up Stonehenge around him all glowed with a purple light, each stone encompassed with different runes and glyphs. Eventually Oz heard a loud bang as the floor started to tear apart and reveal a staircase going down beneath Stonehenge itself. Seeing as though he found the entrance, Oz smiled in glee. Norberta looked down into the entrance with expectation as well. After a little bit of time the light show ended with just a staircase down presented to Oz.
