The homeworld of the Xahean people, ruled by Sylvia Tilly's friend Po, and the site of Discovery's last preparations before leaping to the future.
Xahea is the homeworld of the Xahean people and of Me Hani Ika Hali Ka Po, introduced in the Short Trek Runaway. Po, a young stowaway aboard Discovery, must return home in time for her coronation, and Sylvia Tilly decides on her own to help her get there.
The planet returns in Such Sweet Sorrow, when a new Red Angel signal leads Discovery and the Enterprise to Xahea, now ruled by Queen Po. A brilliant engineer, Po helps Paul Stamets, Tilly and Jett Reno prepare the time suit and crystal before the Section 31 fleet arrives.
