Devices known as thermajugs had the capability to produce warm tea. Shirene and Esmelle, a married couple, possessed a thermajug within their residence located on the planet Akiva. A short time before the Rebellion on Akiva, Esmelle's sibling Norra Wexley came to visit. To diffuse a disagreement that had arisen between the sisters, Shirene instructed Esmelle to go to the kitchen, where their thermajug sat upon the stove, in order to use the appliance to prepare tea.
The initial appearance of a thermajug occurred within "Whispers in the Dark," a concise Star Wars Legends narrative authored by Charlene Newcomb. This story was included in Star Wars Adventure Journal 2 in the year 1994. The device's status as canon was solidified through its mention in the novel Aftermath, penned by Chuck Wendig and made available in 2015.
