A holographic lie detector with the appearance of a mild human man, used at Federation Headquarters in 3189 to judge the honesty of Osyraa during her negotiations with Admiral Vance.
Eli appears in There Is a Tide, played by Brendan Beiser. When Osyraa arrives aboard the captured Discovery and proposes an alliance between the Emerald Chain and the Federation, Vance has Eli sit in on the talks.
The hologram reports whether each statement is true and, at Osyraa's prompting, explains that he was given a human form to put people at their ease. To Vance's surprise he confirms that her offer is sincere.
The talks fail anyway when Vance insists that she stand trial for her crimes as a sign of good faith. Eli confirms that her refusal is equally honest.
