Thats my name too! I'm a trans guy and my dead name I chose not to share, but basically it means the opposite of Eclipse. I love my new name and I've been using it since 2020, I highly suggest this name, I get a lot of odd reactions from people since its different, but also a lot of good reactions (usually from Queer people).
I was really hesitant with my chosen name (which is also Eclipse) since it is indeed rare, but finding it on websites that say it's an actual name makes me really happy! Since, I chose it back in 2021 as a filler name but then I got really comfortable with it! Since, it is really unique of a name so I highly recommend naming your child (or yourself if you want..) Eclipse! If you're just looking for a really unique name that has been barely used in real life people but I'm one of those people!
