No, this was just to get you reacquainted, and give you some room if you wanted to do anything special, describe your clothes, whatever 
Manta is not alone: 2 other guards are with him, and they are way stiffer and professional, although this doesn't look like an arrest, more like an escort.
Together, they lead Roberto towards the throne room. Its doors open, and the chambellan says: As requested by the Crown, the Protector of the Realm, Master of Flames, Roberto of House Flambeau!
The throne room is, as ever, full of people, but much less than in previous occasions.
Soteira sits on the throne in full regalia, crowned, holding her fearsome trident.
To her left, Roberto recognises Thula in light, yet fancy, scales, and Lord Byrrah, still in pants and cloak, still displaying his well-toned bare chest. Slightly behind her and to the right, waits Aubert, wearing the golden mask of poseidon,which sadly makes him all the more inscrutable. And on the right side, there are 2 other merfolk he's never seen before. A plump, noseless siren siren, her legs replaced by a tail, and one of the more monstrous subjects of Soteira, a blue merman with tentacles for legs and beard.
But it is not them who draw Roberto's attention: Further on the right, clothed in green and golden bronze, another human awaits. Tall, handsome, muscular, his blonde hair and beard displaying a square jaw only seen in tales. It can only be Orin.
There's only one way to go, walk to the throne, next to the pretender.
Once Roberto is in place, Soteira speaks, her voice resonating throughout the chamber.
Roberto of Flambeau, Orin Merinitae. It is our pleasure to welcome you into our palace.
We are here to settle matters of blood, alliance, and succession. For too long, the throne has been alone in its trials, the line of succession unsecure.
But today, Herakleion is blessed. 2 mighty champions, both mortal magi, vie for my hand. And though my heart knows its way, it is the crown's interest that must prevail.
Thus, we have gathered our best advisors to answer this question: Who, amongst you, would make the best king?
We do not know. While different, you both have demonstrated your willingness to tie your life to this land, and the many qualities that would make it a blessing to us.
And so, it had been decided, should you so choose, to put you through the old Contest of Champions.
A king must be brave, so you will have to prove your courage.
A king must be strong, so you will have to prove your strenght.
A king must be wise, so you will have to display wisdom.
A king must bring peace and prosperity, so ability to do so will be tested.
Aubert speaks then, in a booming voice totally unlike his usual frail, cracking one
But these champions have already proven their valor, have they?
Thula advances, and says:
I, thula of the guard, says so: Roberto has, time and again, proven his strength before the most powerful ennemies. For him, I claim the trial of Might
The tentacled merman does the same
And I, Llyron of the guild, attests : Orin has brought peace to our city, and allies. For him, I claim the trial of Diplomacy
There is a slight pause, and Soteira answers, looking at Roberto in the eyes
The Crown recognises the validity of your claims. Champions. Do you maintain your claim to our hand? Do you wish to go through the remaining trials?
