Timeros’ loyalty to Arcona defines him. His devotion to the Shadow Clan is the anchor point of his personality, a constant of the Galaxy as adamant and inflexible as gravity.

If his faithfulness has any flaw, it is that while Timeros cares greatly for the idea of his Clan, his view of its members and – especially – its servants is far more pragmatic. The Entar thinks nothing of killing his fellows, if he feels it would benefit Arcona.

However, decades of brutal murder in Arcona's name have left their toll on the Entar's psyche. Timeros lends the entirety of his self-worth to his status as the Shadow Clan's foremost enforcer. Removing that final vestige of a personality would break the Arconae completely.

Timeros is punctual, dutiful and obedient. Whether he is shuffling papers for the DIA or is gutting an enemy with his lightsaber, there is an inhuman, machine-like steadiness to the Elder, as if he were moving to the staccato ticks of an invisible clock. Sometimes it ticks slowly, and the Entar moves with unruffled and balanced grace. At other times the ticks speed up, and his movements accelerate in turn, causing the Arconae to zip about while seeming nevertheless unhurried and smooth. In either case, he moves towards his goals with the inexorable surety, reliability and resolve of a man who lives for his duty.

Timeros is one of the most even-tempered men in the Brotherhood. The Entar can rip out an opponent’s throat without so much as skipping a beat. Where most Dark Jedi draw on the Force by the strength of their passions, Timeros does so through tranquil willpower and self-mastery. In doing so, he has torn out his heart, leaving him nearly emotionless. The Arconae is bereft of compassion and empathy, and while he can be cruel where necessary, he derives no satisfaction from it.

This generally phlegmatic attitude has won the Entar few friends; he is unapproachable, repressed and aloof, defining himself in terms of his duties and responsibilities rather than his friends and relationships. While the Entar cherishes what confidantes he has, his obligations must always come first.

Timeros’ body might be flexible; his mind is not. The Arconae has no discernible vices, not given to drink, women, or even much food; he likewise has no desire for wealth or power. While his ethics are skewed by his mindset, they are also unimpeachable. The Entar’s every action seems founded on straight-line movement towards a goal, without compromise or regard for those that he might hurt. When Timeros makes a decision on what is the right thing to do, nothing will sway him from his task. His methods might change; his goal will not. Persuasion, threats, bribes or outright physical violence: nothing can seem to bend the Entar’s dedication. If he is to be stopped, he must be broken.

When in serious combat, Timeros is a hurricane of aggression. Possessed of lightning reflexes and a natural athleticism, and with no inhibitions whatsoever concerning violence, the Entar’s strikes fall swiftly and surely. In attacking, he is relentless and merciless, not giving adversaries even a moment to compose themselves. When defending, he moves with the utterly-focused surety of a veteran killer, body and saber flitting about to keep him from harm almost without thought. The Arconae dislikes unnecessary displays of power and skill, however, disdaining spectacle and flashiness as gaudy. Ostentatious displays annoy the Elder, and he only moves as much as is absolutely necessary. This can be an issue when he misjudges himself or his opponent.

Timeros’ consciousness flits about his surroundings like a hawkbat on the hunt. Whenever he enters a location, his mind instantly evaluates the terrain, people and objects within it, assessing their potential for violence. As a result, the Arconae can be an inventive and ingenuous opponent, using unorthodox strategies to complement the steady assault of his saber and blasters.

The Elder’s otherwise-focused mind, however, fractures when it comes to considering anything that goes on at longer distances. The Arconae is at best a mediocre military strategist, as he seems unable to conceptualize anything that he cannot directly affect with his blade, mind or blaster bolts.
