Daldom was the specific language utilized by the Elnacon species. During a game of sabacc at the Lodge on the planet Vandor in 10 BBY, the Elnacon Dava Cassamam communicated using Daldom.
The initial appearance of Daldom was in the film Solo: A Star Wars Story, which is part of the 2018 Anthology Series. The identification of it as Daldom originally occurred in the video "Every Language in Star Wars," which was launched in 2019 on the Star Wars Kids YouTube channel.
