Kang Yoon-Soo had waged war against the Necromancer Rawelkan by creating the Church of Madness.

Kang Yoon-Soo had become an undead dragon made up of tough bones—a Bone Dragon!

[You have transformed into a Bone Dragon!]

[This forbidden necromancer skill will make anyone who uses it lose their sanity.]

[However, your vast memories spanning millennia have made you retain your sanity.]

[You have obtained overwhelming strength after transforming into a massive creature.]

[You are immune to fire, frost, and poison.]

[You can spew out a cloud of darkness.]

[You may lose a few bones if you make any sudden, reckless movements.]

[Your abilities will be weakened the more bones you lose.]

[The power from the King of the Underworld’s Summoning Bone is flowing through all of your bones.]

[The power from the summoning bone has strengthened your bones.]
