Llandrin

Llandrin was a bard best known for his telling of the Eiskjarl Karlorn. It is one of the lengthiest and most detailed tellings in the Eiskjarlic Cycle, containing many details not found in other tellings regarding Eiskjarl Karlorn or the other Eiskjarls in the Cycle. The "uniqueness" of many of his assertions have led some to question whether or not his version should be considered unreliable.
The phrase "no other assertions are known" is commonly applied to details of Llandrin's telling.
