This is set before Joffrey's wedding where the Red Viper and his Dornishmen have just arrived at King's Landing, and it is seen from Oberyn Martell's viewpoint.
As Tyrion scampered off to the head of the pack, Oberyn Martell's eyes averted to the colossal sight that was Kings Landing. He remembered it well, in the days of the Mad King, the great white marble that surrounded the castle still glistened in the midday sun, and the city was still crowded as ever. However the reason for it being crowded this time was the camps that spilled out from the Red Keep and into the city itself, most bearing the sigil of a golden rose.
Tyrells. Oberyn thought as he dismounted from his black stallion. "It's so nice to see that the Tyrells have welcomed us" he said sharply, while gesturing at his squire to take his horse. "Ah but they have Oberyn, they are waiting in the court alongside my king nephew and sweet sister." explained Tyrion, "Rest assured they will send their best wishes for your brother as well " , the Imp japed, as he waddled beside Oberyn. " I highly doubt it, the Queen of Thorns will probably say it's justice for what I did to Willas." Oberyn smiled. "Now Tyrion, tell me of Elia. Did the Mountain rape and kill her?" .I seek vengeance.
"I knew nothing of it but rumours, and alas they are only rumours my lor-",
"-surely you know the truth of it now Lannister", Ellaria's snake-like tongue weighed in, her eyes a faded yellow. "Ellaria, hold your tongue, Tyrion has admitted to only knowing rumours" Oberyn said abruptly, while realising they were getting close to the throne room. He could see the thousand blade chair, the Iron Throne, about 5 yards away with a blond boy king who sat there with a lopsided crown, his impatience growing.
"Oberyn, it has been a long time since I've seen you" Cersei said as she kissed him spitefully on his cheek, "Too long m'lady" Oberyn replied.
"I would like you to introduce to my son Joffrey, the king", she said pointing towards the blonde boy. Oberyn knelt, "Where is the other one?" Joffrey asked as Oberyn got up and withdrew his jet black hair from his face. "He has become weak your grace and wishes to stay in Dorne for the time being, I have come to replace him on the small council if it pleases you". Joffrey briskly turned his head around to Cersei and then to Tywin, who nodded simultaneously. "You have my permission to the small council, my wedding and kings landing. I hope you enjoy your time here"
"thank you, your grace" he replied, knowing fully well Joffrey's line had been rehearsed. Oberyn then continued on meeting and greeting the nobles of Kings Landing, who all either expressed their excitement for Joffrey's wedding, sent their regards to his brother or just generally talked of the war and what was left of these other self-proclaimed kings.
He then saw the beast of a woman Olenna Redwyne, the Queen of Thorns. She was not ugly to look upon but time had not served her well. Her frail wrinkled skin was an example of this, which seemed to retreat under her rounded chin. There was anger in her eyes and spitefulness in her tongue, Oberyn could tell, as there always was with the Queen of Thorns.
He almost turned away, if it had not have been for Lord Tyrell, who spoke up,
"Oberyn what a surprise to see you here, instead of your brother. Come, let me introduce to the new additions to House Tyrell". At least Lord Tyrell has shown some courtesy. "This is my daughter Magaery",the girl gave a smile as she looked at Oberyn with her chestnut brown eyes. She could not have been old, as she had the sweet innocence of child about her. Her dress colour was turquoise with flowers interwoven on the fabric.
Oberyn gave only a quick nod to Magaery as Lord Tyrell had moved on,
" This is my third eldest son, Loras. He is part of the Kings Guard". Oberyn shook hands with Loras a little longer than intended, as Oberyn couldn't keep his eyes off him. He was well built, this Knight of Flowers, as his chest seem to thrust out his own garb. His blond curly locks were like golden sunsets, many he had watched as a child in Dorne. The curls we not too dissimilar of waves either. He also had brown eyes but his were fiercer. His face was well shaven and showed a faint smile.
"It is a pleasure to meet you Ser Loras",
"No it is I who have the pleasure to meet you Oberyn Martell"he expressed, with such conviction that Oberyn believed it was sincere.
Oberyn felt a tap on the shoulder then a cold whisper from Ellaria, "You must excuse me and my men Ser Loras as we are in need of much rest after our journey, it was nice to meet you" Oberyn said, while his Dornishmen ascended out of the throne room. The Knight of Flowers, he thought, the Knight of Flowers.
