So actually this was meant to be a real intro for Pyres of Remembrance. The main problem was trying to figure out what happened next (a bombing run on the Valor) and how to make that work in THN format, which turned out to be too complex. Another issue that lead to it being scrapped was the inability to reset it properly for looping, so the battle intro was made to replace it. I also think it's likely a lot of people were sick of hearing Bretonia Battle music on the main menu after several years of the Leeds intro screen.
