I want some advice

I'm in the process of making a sword and I was going to inscribe some elvish script into the blade. take note that I wan't this to be close to perfect. I was thinking something along the lines of "The Sword of Blue Fire Brings Hope!" in Sindarin. I think something close to what I'm looking for is "Megil na Luin Natha Onen Estel!" Am I close and is my grammar right? finally, do you have any suggestions on changing the wording? I thought about using the word "Lacha" instead of "Natha" but I don't know Sindarin grammar very well at all. Can you help me out? Thanks!

My translation would be, “i vegil naur luin tôg estel!”

Got the ok off of someone I trust (thanks Elaran) so I’m pretty confident.

As for the lettering you have two options: the traditional alphabetical rendition of Sindarin: the Mode of Beleriand, and the general tehta mode.

M.o.B.: i vegil naur luin tôg estel!

General: i vegil naur luin tôg estel!

Always happy to be of help,
