makes her and aiden's lifespan tied together, essentially she'll live as long as aiden lives and if she dies, he dies, it also increases her magical power exponentionally, thus aiden more or less extended her life by at least a thousand years but more importantly, also made her his weak point, what angers her most about it though is he did it without even consulting her, she eventually get's over it but it takes a while, oh and for what it's worth, dragons mate for life, thus if she died in like 50 years, he'd be alone for 1000+ years.
