Three hours of chanting and weaving her wand as well as offering her blood along with the blood in the three vials in exchange for various different layers before the small break finally appeared. Barely big enough for her and her little boat to slip through. She had literally and forcibly keyed herself into the wards temporarily. Something no one has done in centuries she was certain of. You see, Azkaban wards were unbreakable... so she couldn’t even attempt that nevermind that it would trigger every alarm the moment she even tried. But to key herself in... without the Minister of Magic and Heads of the DMLE and DOM... well that was quite a wonderful feat as the three had to jointly key and maintain all Azkaban wards. Having their blood helped naturally.
