Chain of Thrones - Roleplaying Recruitment

Lorek - Led by Melek Ib-bar and Goronak Ilorik, the Lorek Crimson Chains consist primarily of former SIU agents and associates. In many ways they are one of the largest surviving elements of the former Hegemony, but in the aftermath of the Reaper War they have become intimately connected with the government of Lorek. They primarily provide bodyguard, honour guards, and other security services for corporations, diplomats, businessmen, and honored guests, and are among the best-trained soldiers left in the Confederacy. Despite this, their true motivations remain veiled in mystery, and rumors of their connection and involvement with the alleged ‘deep state’ are hard to deny given their makeup.

Chresk - Led by Alto Ord’Narak, the Chresk Crimson Chains are the smallest faction of survivors, and use hidden lab facilities and stockpiles to provide banned weapons and armaments to whoever can afford them. Several of the Na’Hesit governments in the Kite’s Nest owe their survival to weapons provided by this group, who have since leveraged this into continued technological advantages. Along with their proven connections to the Na’Hesit, the Chresk Chains are alleged to have connections to the Erszbat Cabal and a number of major mercenary groups.

Cartagena - While the Lorek faction of the Chains approaches legitimacy, the Cartagena faction, led by Ashtor Sam’klar and Joral nabOrcas, has taken the opposite means to survival. Leveraging their superior arms and equipment into a strong position among the gangs of Cartagena, this faction has expanded rapidly to include numerous smaller gangs, batarian or otherwise. By far the most obviously ambitious remnant, the Cartagenans have extensive connections with the various clans of the Camalan Grusto and this gives them a reach which extends well beyond the station itself.

The Ascendacy - Khar’shan is the heart of the batarian people, and the new government of the motherworld intends to keep it that way. The Crimson Chains have gone beyond mere breaking of the Pillars to threaten a civil war at a time when the very souls of the batarian race hang in the balance, and the Ascendancy has made their move long before that happens. While their involvement remains under veils of secrecy for now, they have no intention of allowing the Confederacy to shatter before it has fully mended. Order must be maintained, all must know their place, and the Confederacy must be permitted to thrive under the guiding hand of Khaljah.

Which of the factions is the closest aligned with the Ub'Hesit?

Just throwing it in there. Even if it seems this'll be more humans than blinks.
