Glenna is a guildmaster in Might and Magic VI: The Mandate of Heaven. She can be found at the Adept Guild of Spirit in Freehaven.

She teaches basic spirit magic and meditation for 150 gold each, though the price can be reduced with the merchant skill. She also sells all spirit magic spells. She will have twelve spellbooks for sale. They are selected at random, and duplicates will happen, so she might not have all spells at the same time.

To use her services, the party must first purchase membership to the guild from Bishop Iquisitorio or Wilma Rothwing.
