Mythomagic

Background
Mythomagic, Inc. is the production company of Rick and Becky Riordan. The former is known as the author of the Camp Half-Blood series (Percy Jackson and the Olympians, The Heroes of Olympus, and The Trials of Apollo), The Kane Chronicles, Magnus Chase and the Gods of Asgard, and Daughter of the Deep, as well as for his Rick Riordan Presents imprint. The company is named after a fictional Greek Mythology-based card and figure game that some of the characters like to play in the Camp Half-Blood series.

Logo (October 12, 2020)
Visuals: On a background of swirling dark blue and magenta smoke, we see a pen, likely Riptide (see "Trivia") draw a line made of gold, trailing behind it an aurora-like magenta mist. Another angle reveals that Riptide is actually writing in gold the cursive text "Mythomagic". The finished text settles into place as Riptide draws an arc from right to left (reminiscent of the 1985 Walt Disney Pictures logo), turning into its sword form and taking place of the "t". The tip of Riptide's blade and the "c" sparkle.

Trivia: This logo seems to be a reference to the beginning of the first Percy Jackson book, The Lightning Thief. When, at a field trip to a museum, Percy's pre-algebra teacher turns into a Fury and starts to attack him, his Latin teacher "Mr. Brunner" (actually the centaur Chiron in disguise) throws a pen at him, which turns into a sword. Percy continues to use "Riptide" (Anaklusmos in Greek) as his weapon for the rest of the series. It changes back into a pen when not in use.

Technique: CGI.

Audio: Pencil sounds for Riptide writing (even though it is a pen), a triangle ding, and an ambient note.

Availability: Posted to Rick Riordan's TikTok and Twitter accounts on October 12, 2020, and will more than likely appear on the company's productions, such as the Disney+ Percy Jackson and the Olympians series and the Netflix film adaptation of The Red Pyramid. It can also be seen on the company's website.

Legacy: This logo seems to symbolize Rick Riordan finally getting into film and television production after years as an author, as it focuses on a pen (Riptide) and turns cinematic.
