The Hollow Hills (If you like Arthurian stuff)
Greenstone
Merry Sun Rising
(insert here: favorite bird, tree, color, whatever) Talisman
Hazelnut (The nuts of wisdom) or Hazeltree
Dragon's Tor

Avalon is taken, I believe. Maybe Elixir as well.

That's all I can think of right now.

You can always do exercises, like choose a color, tree animal/bird, theme, time of day, and try to work those into a name.

Good luck,
