Please add tropes here, needs much expansion and editing magic.

"Nex: Don't touch my daughter."
 * Anti-Hero:
 * Nex is somwhere between a Type III and Type IV, as he's a cold, bitter, ruthless, jaded tyrant but he's also trying to prevent Caladbolg and folowers from bringing ruin to Both worlds.
 * Fallen Hero
 * Xix is a Type II; Driven by his desire for revenge against Nex but a good person at heart.
 * Asskicking Equals Authority: Word of God states that Nex is second in power only to Big Bad Caladbolg.
 * Berserk Button: Nex displays varying degrees of tolerance for the usual antics that go along with politics and court intrigue (i.e. plots, deceit, back-room deals, etc). Openly rebel against him however, and all bets are off; He will kill you, and anyone else who tries to stop him.
 * Establishing Character Moment: As Nex, the first thing we see Jae-Hyuk do is ruthlessly order The Purge of a village of suspected rebels — men, women, and children alike are all put to the sword. He also chops off the arm of a soldier who questioned his orders. He's not so sweet anymore.
 * First Episode Spoiler: It's not until Chapter 4 that Nex is confirmed to be Jae Hyuk.
 * Lonely at the Top: Nex lives this trope, as the only person he really trusts is Depore. The tragic part of this is that Nex is actually an inverse of this trope. He never wanted power, much less the position of Regis, but was basically shoehorned into it due to circumstance and the actions of others interfering with his life.
 * The Chains of Commanding: Hence his bitterness.
 * Papa Wolf:
 * Papa Wolf:

"Depore: Jae Hyuk... Nex: Depore. You know I threw that name away a long time ago."
 * Star-Crossed Lovers: Nex and Serin.
 * That Man Is Dead:


 * Used to Be a Sweet Kid: Nex, A.K.A. Jae-Hyuk as shown in Immortal Regis.
