Reg, regarding the note:
One of them introduces himself as Vegtam in "The Song of Vegtam."
Vidar is Odin's son, "his projection."
Vegtam = Odin, Vidar "the Silent" = Odin's son, "Odin's projection."
By the way... If you type the word Vidar into Wikipedia, you'll get a rather interesting article.
http://ru.wikipedia.org/wiki/Видар
"On the day of Ragnarok, according to the prophecy of the wise Norns, the goddesses of fate, the giant wolf Fenrir will kill Odin, after which Vidar will kill him. The ancients considered Vidar to be the personification of the virgin forest or inexhaustible natural forces. Silent Vidar connected the gods with the forest and nature. This god is destined to survive Ragnarok and then rule in the renewed world."
Arandor's avatar is a minstrel from the Ragnarok game.
