A set of runes that appear in the [[Ico]] video game. Each specific rune corresponds to a letter in the English alphabet, usually derived from the first letter in the word that the rune is a picture of (for example, the rune for "A" is a picture of an [b]a[/b]nt.)

In the first playthrough, [[Yorda]]'s speech is subtitled with these runes instead of English, but her speech is subtitled in English on a subsequent playthrough.

In-universe, it's the alphabet used for the language that Yorda and [[the Queen]] speak, which is different from the language [[Ico (character)|Ico]] speaks.
