Zephyros

A cloud giant who ferries the party in his flying castle, taking them to Golden Fields. The interior is lined with bookshelves and maps. He gifted Toz a map of Faerûn and Fiz found a small book — Giant Runes of the Realm — that grants advantage on Arcana checks for giant runes after ten minutes of study. He can be reached again via an animal messenger arranged by Baros Ravenkind in Silverymoon.
