Astrapi Xenowyrms were released on June 27, 2015, alongside the Chrono, Gaia, Mageia, Pyro and Thalassa Xenowyrms as part of the "June Release 2015". This release was the first to introduce into Dragon Cave. Under the old Breed sort, these dragons sorted as "Xenowyrm 5" ("5" indicative of the Alpine habitat). As of August 14, 2016, they now sort using their Encyclopedia name of "Xenowyrm (Astrapi)".
