Isca's greatest moment came when she was able to help stop an invasion of New Maraqua by the violent and notorious Captain Scarblade. King Kelpbeard, whose trust she had lost by recruiting the aid of her surface dwelling friend, applauded the effort of Isca and her friends. After playing a defining role in the kingdom's victory, Isca and her sister Caylis were warmly welcomed back into Maraqua.
