Ervic is a major character in Glinda of Oz. Displaying "courage, cleverness, and ingenuity," Ervic is often considered one of Baum's strongest male characters (as the author's male characters often tend to be ineffectual).
When Queen Coo-ee-oh launches her submarine attack on the Flatheads, Ervic is one of the young men in her flagship. The Flatheads quickly dispatch with Coo-ee-oh, as they simply wanted revenge on her personally, but as she is the only one who knows the magic to get back to the submerged city, the young men sit in the boat, unsure what to do. Ervic is approached by the Three Adepts at Magic who are stranded in the form of fish. They wish him to catch them in a bucket and to follow their instructions, and that if he does so, he will save himself, his city, and his companions. They help him get the boat to shore and have him carry the bucket to Reera the Red. Reera is a beautiful young woman who practices Yookoohoo (transformation-only) magic for her own amusement. Reera is interested by his impertinence with her, and very shrewdly manipulates her into restoring the Adepts to human form, taking quite a bit of time and waiting for her to ask permission to transform them several times. The Adepts are able to assist the raising of the city, and with Coo-ee-oh gone, Lady Aurex is named Queen of the Skeezers by Princess Ozma, and for his valiance, Aurex names Ervic her Prime Minister.
