I forgot to gloss Ægishjálmur (the icon). Literally, "helm of awe." In more mordern times, it's part of a spell of protection "against taxes and the depredations of the rich" -- carve it on a thin sheet of lead and slam it against your forehead while reciting the cantrip and wham! you're protected as long as the impression of the sign remains on your skin. In the Eddas, though, that's the name of Fafnir's helmet -- anyone who saw it was overcome with fear, until Sigurd overcame the overcoming.

For pronounciation, in Icelandic the soft g (when followed by i or e) is a glottle stop: a half-said y, or an apostrophe; á is ow; and j is of course y in true Scandinavian style. Stress always first syllable. Thus, AE-'is-hjowl-mur. (Unless you're speaking colloquially, in which case final -ur is often slurred to -ish.)
