Ileen is a typical Rohirrim of looking somewhere above 30 years of age, blonde and blue eyed. The beauty of her mother and the strong constitution (for a girl of her age) inherited from her father result in a strange combination. For sure she is not the type of fragile beauty you find dancing in ballrooms but she has a fair figure that inspires trust and decision: a good person to have by your side. She is voluble for a Rohirrim, inquisitive and eager to make friends and offer a helpful hand. She enjoys  remembering or planing adventures and deeds of courage, and listening to the stories and wisdom of those older with great respect (even is she does keep her own opinion on things like not sharing the mistrust in Elfs and Wizards common at Rohirrims)

After the first adventures she faced by herself during the travel to Bree -that almost cost her life but also brought her the friendship of the she-elf Driadriel- she presented her letter and was accepted by Lord Ehris Tiubar in the Riders of Riddermark Company.She is now eager to prove herself, improve her combat skills and make new friends between this skilled warriors she admires so much.

One event, when in her early 20s, that got her in a true personality crisis was a commando-style (modernly-so-to-speak) mission in Fornost she did with her fellow Riders, about which she has a partial amnesia on the final confrontation with  a ghost-spirit-strange evil presence . She told nobody but Cendryth of this as she feared that those following her in battles would lose trust in her decisions if she told them she can't remember what she did in the battle, and by that her military advancement would be jeopardized. Still she realizes she is not fit to command if she cannot control herself but does not want to risk loosing respect on this. After a deaf's argument with Cendryth, who proved a benevolent friend but unable to understand her dilemma and suggested only "accept your limits", a thing Ileen refused from start to do out of pride and ambition, she made her decision to test herself alone, without putting any other life in danger, until she is sure she surpassed her weakness and can keep her clear judgment no matter how dreadful the opponent force is. The first step was a Othrongroth foray to face alone the Wight-Lord of the Barrows. She did prevail but also understood that she needs tougher challenges to be sure of herself. So for a while and and in complete secret Ileen changed from the crowd-loving and sociable officer she usually is into a loner seeking her true self, hunting her own demons in the real demons out there. Few challenges of what fate offered since then remained unanswered -even against Lord Ehris's will- and not much other than words of huge ambition and a deep sadness under a thin smile was her answer to any question about her change. Some trophies from this adventures are placed on the walls of her private bedroom to remind her of what has been proven already and give her trust in herself. But her deepest fear is still out there to be faced.

Years passes and, once returned to Rohan, she lost her main purpose. A older wound at her right leg proved to bothering her again without much reason: she walks with some difficulty and has a hard time getting into her saddle with no help. This changed some of her merry mood and made her polite but reserved, especially with new acquittances. She retreated to a hunting-house property of her family, she got it refurbished for more comfort and she seems to be  keeping to herself. One servant, newcommer to this parts, a few years younger than Ileen, is the only person she sees on a daily basis and solves supplies and housekeeping.
