"Athelwulf" has been my username for almost everything since the summer of 2004. It is a rough transliteration of two words from a conlang of mine: äþel "noble", and wulf "wolf". At the time I made my name, it was Âðelwulf in my conlang, and sometimes I wrote it like this. Since then, my conlang's orthography changed, and my name would now be rendered Äþelwulf.
