Regarding the name
It is incredibly confusing that the anniversary phoenix is called '1st anniversary phoenix' when they will in fact be returning next year. Change it to something more generic like anniversary phoenix, annual phoenix, celebration phoenix, or what have you, but listing it as the first anniversary phoenix when it is not limited to the first anniversary is incredibly confusing.
Edit to add: Especially comparing it to something like the Kickstarter Krane which is very much exclusive to the kickstarter and now retired. Having a 1st Anniversary Phoenix implies on many levels that the phoenix will be limited to that event. This inconsistency just adds to the confusion imho
Regarding the description
The description is a literal quote from Tolkien's work without any crediting. I think it is unfair to use their IP without credits and it should be changed to something original instead. Perhaps the description can also be used to indicate the phoenix was introduced during the first anniversary; this would allow for easy differentiation between companions released in subsequent anniversaries, but with more room as to not make it confusing on whether it is retired or not
