Danaerys had become mistress of Astapor and therefore, controlled the production of valuable Unsullied. Currently she had 15,000 Unsullied, 10,000 freed slave militia, and 100 Dothraki to her name in addition to 3 young Dragons.
It was not enough to seize Westeros, not by far. It might be enough to seize Yunkai and Mereen though. Unfortunately she was now locked in a war with the General Hobaq zo Hobaq of New Ghis.
