Aliasing borelian → tetton
Link to alias
Reason:
It's a bit tough to research, as it's a fabricated species primarily drawn by a single artist who keeps little/no easily searchable documentation on such a change, but judging from the fact the artist's only locatable artwork marked as "Borelian" are from 2013 or earlier, and similarly "Tetton" is only found on artwork from 2014 or later combined with the fact that they appear to share near-if-not-exact biology leads me to believe that these are both the same species, and that Tetton is the current name. However I notice new instances of the Borelian tag have been appearing, and unless someone can confirm that they are in fact separate species it would make sense to have them all in the one searchable location.
