Let Me Be Thine Villain

You have had enough of being the thankless do-gooder. Now let the kingdom see how much they needed you as their protector and let them weep that you are now their enemy. My entry into this month's journey focused scenario contest. Your villain arc has began; Will you uphold your oath to end the Blackwood line? As usual the art is custom made, any comments or suggestions are greatly appreciated, and if anyone wants to suggest a story for me to make I'll probably do it. I mainly make fantasy and romance scenarios, but am open to suggestions outside of those veins.
