Stannis Penrose

Early Life
Stannis Penrose was born in 361 AC, the firstborn and only child of Lord Rogar Penrose and his wife, the Lady Alysanne Baratheon, sister to Lyonel Baratheon, Lord of Storm’s End. A spirited, lively and strong boy, his parents both doted on him. His early childhood was a happy one, by all accounts, and free from any major calamity. When the King lead the realm to war in the Stepstones, Lord Rogar answered the call and joined the Westerosi host. For many moons, Stannis and his lady mother feared for Rogar’s safety, but his lordship thankfully returned unharmed to Parchments at war’s end. At the age of ten Stannis was named his own father’s squire.

Lord Rogar, noted for his martial prowess, had made sure to put a sword in Stannis’ hand as soon as he was old enough to properly hold it. His instruction in the arts of swordplay was only intensified upon his father’s return from the Stepstones. “If there is yet another war, I mean for my son to be prepared for it.” Lord Rogar was heard to say. Stannis took to his rigorous training regimen with gusto, and oft spent entire days in the yard, fighting pages and other squires and eventually even his father’s sworn knights, men tried and tested upon battlefields aplenty. Likewise, being a lord’s son he was placed on a horse from an early age, and found that he loved horses and riding. Any time he didn’t spend practicing his skills with the sword, he spent in the saddle, riding to and fro across his father’s domains.

Knighthood
In 378 AC, when Stannis' uncle Lord Baratheon turned forty-seven, a tourney was held at Storm’s End in celebration. Stannis, preferring the sword to the lance, opted not to compete in the joust, instead entering the melee. During that fray, many brave warriors showed their mettle, but in the end Stannis emerged victorious, having beaten his final opponent and cousin, Steffon Baratheon after a fierce fight. As a reward for his prowess, he was knighted by Lord Lyonel himself. When a year later, in 379 AC, Prince Daeron and Lord Baratheon rose in rebellion, Lord Rogar answered the call. His levies rode to join the rebel army, and Stannis rode with them. He was present at the battles at Summerhall, Skull Valley and the Redgrass Field.

Lordship
When the rebel forces attacked King’s Landing, Lord Rogar led his levies in the streets, whilst Ser Stannis joined the Prince and Lord Lyonel in the dash toward the Red Keep. As the rebels clashed with the Kingsguard in the throne room, Ser Stannis, together with Lord Selmy, fought Prince Aegon. The fighting in the city was bloody and fierce, and despite the ultimate rebel victory, Lord Rogar was killed.

His father’s death saddened Stannis deeply, but he nonetheless took up the mantle of Lord.
