My psientists had determined that there was an artifact of great power under a portion of her lands, non magical, and offered my troops to supplement Axia's in exchange for the plot of land. Suffice to say things did not go precisely as they should have. My sources have recently reported that Axia is dead, and that a lesser known ally has taken over her kingdom, but I have found neither verification of this nor how she died. If she is dead, it will throw the balance of power to the wind. That she was at least a millennium old before her death.
Some secrets are better left secrets.
In the past, we have had little luck insinuating agents into her kingdom. If she truly is dead, perhaps that will change.
