Exactly like it appears, duh. Nobody has ever managed to pronounce Gildan incorrectly so far in any of my conversations with folks from my Guild Wars alliance over Ventrilo/Teamspeak, and this is factoring in that they come from all over the bloody world.
Bladeborn is of course just two ordinary words stuck together and pronounced just like they would be if they weren't - thus the pause a hyphen or space would indicate isn't really needed. I imagine somebody might find a way to mispronounce that, but if you can read English you are probably going to work out what it's supposed to mean.
