You say, 'Hail, Holdegar Bairdun'
Holdegar Bairdun says 'Well met! I am Holdegar Bairdun, last of the Bairdun line of gem-polishers. I spend my blissful eternity here in Brell's Rest practicing my trade, which means polishing up the green magic gems that are sometimes carried around by denizens of the Underfoot. If you could, er, cajole a few of these gems away from their owners somehow and bring them to me, I'll give you an improvement to one of your advanced magic spells.'
Upon handing him a "Trade-In Gem: _____ Rk. II", you receive in return a No Trade Rk.II spell, song or tome. See Underfoot Rank II Spells for more information.
