The Truth Seekers is a secret club that appears in Dragonslayer.
The Truth Seekers is a secret club formed by Violet and Daffodil which aims to find out the truth about everything in Valor. It operates more like an after-school hangout than a formal organization, but they only invite those who are interested. They have a secret handshake that involves touching their own forehead with both of their hands, and then touching another member's forehead with their both of their hands. The Truth Seekers adopt a symbol of matching dragon wings, which are drawn on the back of their hands. This is done because others can associate it with being Wingwatchers, but it is actually their secret symbol.
The club is first mentioned when Ivy tells Violet and Daffodil that Pine was banished unfairly and about the secrets Heath has been hiding from Valor. Violet tells Daffodil that Ivy should join them, and Daffodil argues with Violet about mentioning it in front of Ivy without her consent. Ivy then thinks back to all of the "secret clubs" formed by seven-year-olds that she had joined and was surprised she hadn't heard about the Truth Seekers before. She also worries that the Truth Seekers will quickly fall apart like the other "secret clubs." Eventually, Daffodil and Violet decide to accept Ivy into the Truth Seekers club, and then tells her their aims. This starts a friendship between Ivy, Daffodil and Violet. They then get matching dragon wing symbols.
