Admiral Daro'Xen vas Moreh

Admiral Daro'Xen vas Moreh is a member of the quarian Admiralty Board during the events of Mass Effect 2.

Daro'Xen vas Moreh is voiced by Claudia Black.

Tali: Treason
After Tali'Zorah vas Neema is accused of treason against the quarian people, Admiral Daro'Xen is one of the three admirals present as judges, along with fellow admirals Zaal'Koris vas Qwib Qwib and Han'Gerrel vas Neema. She is described by Han'Gerrel as being on the fence regarding Tali's treason and refers to the trial as "a farce born of fear". Though she has no interest in the trial, she knows that its subtle purpose to stir the Migrant Fleet to reclaim their homeworld.

Xen describes Zaal'Koris as a coward and Han'Gerrel as "an aging warship". She sees Han'Gerrel's plans for war with the geth as foolish and self-destructive, but she has no qualms about experimenting on active geth. Her reasoning is that a starship can travel faster than she can and can make independent decisions with the right programming but can still be broken down. She reveals that she wishes to return the geth to the control of their rightful masters, the quarians who originally created them. If Legion is in the party, Xen finds it fascinating, originally assuming it to be a simple mech built with a geth shell, more so that it chose a name, stating wistfully, "the things I could learn under slightly different circumstances", to which Legion responds, "this platform is not available for experimentation". Furthermore, Legion responds to her plans for controlling the geth by describing them as "unsound" &mdash; a statement with which Tali'Zorah agrees.

After Tali's trial is complete, Admiral Xen sends a message to Commander Shepard's terminal that she did some searching of her own aboard the Alarei. She cryptically states that had Shepard presented the results of Rael'Zorah's research, humanity would've reaped the benefits, instead, they "will watch from a distance as the quarian people reclaim not just their homeworld, but the largest synthetic army in the galaxy".

Note that if Tali's father is outed during the trial, Xen (if spoken to) will still chastise Shepard for revealing the nature of Rael's work in public. In this case, it is likely the research will be purged, or at least be too politically volatile for her to take advantage of.
