Haha... He's suggesting that it's probably a custom job. Where did this come from? I wouldn't be surprised if it were a font with alternate characters. On the other hand, it could indeed be "custom."

Sorry, I was thinking this is handmade, or custom.
I might be wrong of course. Where is this from?

That's Lys Calligraph, aka Lysandria aka Lorrene. You can see it on Mike's script ID guide (scroll down, it's on the bottom right of the page). It is not commercially available to my knowledge. It is available as freeware for PC only. This is funny, I was just looking for this font too. It's a beaut .

Lysandria was a Fontbank font. Other versions include David
Rakowski's Sisman, Brendel Informatik's Windsor Sword and
Castcraft's Opti Lord Swash.

Thanks Mike, I'm glad it's still around and not consigned to the dustbin.
