The Burning Defender's Medallion is a new toy added for  Midsummer Fire Festival.  It will cost 500 x  Burning Blossom.  Your character model will be shapeshifted into Burning Defender (click View in 3D), which looks exactly the same as the model for Seething Pyrelord for a duration of 10 minutes with a 2-hour cooldown.

The Toy Box allows players to store vanity items in a manner similar to companions and mounts, without requiring physical storage space. The Toy Box will accessible through the user interface, as part of what is currently the Mounts And Pets interface.  The Toy Box is account wide, so you will only need to acquire Burning Defender's Medallion on one character.  The level of the character does not matter, though you will find it easier to quickly accumulate the needed amount of the blossoms on a higher level or max level character.
