Andrelious, having seen many years of conflict of various types and scale, is well versed in the art of alliances. He has no qualms about forging a temporary alliance with the most unexpected of people, should they have a common enemy.

However, this alliance may prove to be not only temporary, but volatile as well once the common enemy has been defeated, as Andrelious would think nothing of betraying his former ally should doing so prove beneficial.

Andrelious, whilst much warmed towards his colleagues than he was previously, will still abandon an ally if they become too much of a burden. He will fight tooth and nail to protect each and every of his comrades whilst on a mission, but those who become wounded and unable to continue without endangering the mission may still find themselves left behind by the ex-Imperial.

Since marrying Kookimarissia, Andrelious has become incredibly protective of the Alderaanian female. At times his thoughts of her have occasionally distracted a little from the mission. Andrelious has also extended this protectiveness to his twin daughters. Additionally, the Sith has discovered an elder daughter, Saskia Ortega, the product of an unfortunate rendezvous. Whilst he does not yet have a real connection with Saskia, the ex-Imperial has vowed to change this as time goes on, and has already begun to consider the Cirrian as part of his family.

Even after helping Pravus and the Inquisition, Andrelious was present of Karufr when Jac Cotelin ordered its bombardment. Having survived, Andrelious considers himself to be a great deal stronger, and is increasingly sure of himself both in and out of combat. This leads him to risk both his own life, and those of his subordinates, especially in seeking revenge on Pravus, his Dark Council, and the Inquisition.

Whilst deadly with a lightsaber or blaster in his hand, Andrelious has shaped his command of the Force to the point that he is never truly unarmed. He relies mostly on Force Lightning, and to a lesser extent, Telekinesis, to attack his opponents.

Although aware of its draining effect, Andrelious will often exhaust himself through overzealous applications of lightning.

Andrelious is renowned for his brutal killings of his enemies. He always appears to be looking for new ways of not just killing, but ensuring a great deal of suffering among those that become his prey. One of his favoured examples is to sever the windpipe of his target with his lightsaber, leading to a slow, suffocating death. The drawback of this is that Andrelious will sometimes over-analyse how to kill somebody rather than getting on with the job.
