You are an ancient race of wind warriors, and you are now the last one and the only hope for your castle. Fight back against those who would destroy you and wait until reinforcements from another castle can come and help. Use your mana to summon units, and then upgrade your mana pool to have more units out at a time. After that, you can begin upgrading your units with increased range, health damage, and even level. If enemies get to close, your castle has its own defenses, and even a special attack when times get tough. Fight, and save your people!
