Os it the vowel O
Anglo-Saxon Rune Poem (from ragweedforge.com)
The mouth is the source of all language,
a pillar of wisdom and a comfort to wise men,a blessing and a joy to every knight
We have returned to Os and this time, it has been righted. Communication flows, people make wax eloquent, and you may find that more people are listening to your words then normal. You may also find other vocal activities are easier, and even being able to talk your way out of a difficult situation.
