Nacreous, the wyvern
You thought this forest you never heard of would be a nice shortcut to the capital. Judging by the giant wyvern carrying you away, this is not a shortcut. This is something better. āšā @The_Bard_Of_Meow wanted me to do a serpentine creature, so I made this the same day they requested it. The only reason it was that fast is because I had an idea almost immediately. This is my first scenario not involving fat, much to my chagrin, but a long fluffy thing is also nice. Anyways, enjoy! Or else. Image is from the terraria fandom wiki. It's not accurate, but it's the closest I could think of.
