Tall, very muscular and fair haired, with hazel eyes. His features are pleasant, homely and normally set in an affable expression of obliviousness.
A skilled horseman, good swordsman and excellent lancer, when he goes set for battle or danger he wears his suit of full chain with leather helm over a chain coif. His steed is a magnificent charger called Varriaur, who fights under him and is as brave, (and some say arguably cleverer than he).
Youngest son of the Baron de Puignon from Vardonne, Gaston is brave, generous and honourable to a fault, which is a dangerous combination when mixed with his idealism and heroic idiocy. He doesn’t even suspect that his betrothed Lady Rosanna de Malveaux is less than virtuous and innocent, which makes him the only one in his homeland to think well of her. He killed a lion armed only with a dagger and in light leather hunting armour to prove his love, and now his betrothed has set him the exponentially more tricky task of killing a wyvern singlehanded and returning with its head to present to her. At least this time she allows him to go armed and armoured properly; which is big of her.
His honour demands that if he wants her to marry him, he must undertake the Tasks of Devotion she sets him. Most of the time amongst lovers these tasks are non fatal and often more courtly, but in this case the difficulty of these Tasks and their danger has elevated him to some kind of esteemed status amongst Vardonnais Men of Honour and Lady Rosanna as a wicked shrew or demanding object of desire (depending on whom you speak to).
He loves music and dance, more so for he is not accomplished with either, and tales of valour and bravery are meat and drink to him.
Update: Now having forsaken his (suicidal) quest to win Rosannas heart, he has found love with the Courtesan Maia of Turlavayne, and they have been wed in an elegant ceremony incorporating elements of both Sensu and her aspect as the Silent Lady. He has also been subsequently adopted into the House of Count Civar de Ricard, as his own family have disinherited him; no great loss since they were happy to see him die for matters of family “honour” and gain.
