ASOIF: Targaryen Heroes 2

Both the Dothraki Horse Lords and the Unsullied have pledged to follow House Targaryen and their leader, Daenerys, the Mother of Dragons, into Westeros so that she can reclaim the Iron Throne, as is her birthright. While the Dothraki and Unsullied have vastly different styles of fighting and command, they are both extremely effective. With powerful allies at her side, there is quite a strong chance that Daenerys will be in control of Kings Landing eventually.
