A woman of the deuterium mining colony harassed by Klingon marauders, who tends the settlement's sick and injured and helps persuade her neighbours to accept the Enterprise crew's help.
E'Lis is one of the colonists in the Enterprise episode Marauders, set in 2152. She acts as the settlement's healer, caring for miners with what limited medicines the colony can afford after the Klingons have taken their share.
She is more open to outsiders than the cautious leader Tessic, and trades with Enterprise for medical supplies. Her willingness to speak frankly helps Jonathan Archer learn why the colonists have so little deuterium to spare.
When the crew offers to teach the colonists to defend themselves, E'Lis supports the plan and takes part in the preparations that end with Korok's Klingons being driven off.
