Like they did in WotL?
Open the WORLD_MAP_1.00 workbook, which you can find either via searching or as part of my workbook collection. Find the column for Zarghidas Trade City and this line in particular:
01009C0001000100A10001000100A30000000100100201001900DA000100
Broken down, this is:
'Save Cloud
01009C000100 //Have Summoned Cloud
0100A1000100 //Have Bought Flower
0100A3000000 //Have not Saved Cloud
010010020100 //Murond Holy Place is open
1900C8000100 //Play 00C8 on arrival
Delete the check for Murond Holy Place then apply the World Map Edits to your ISO, and you can recruit Cloud as soon as Zarghidas is open, assuming you meet all the other appropriate conditions.
Thanks for the quick response.
