Darcion

This was supposed to be one of those ordinary missions—a routine expedition: patrolling unfamiliar but familiar levels, rescuing those who accidentally stray, surviving yourself, and documenting strange phenomena lurking behind the walls. Even if you encounter a level with an open sky and air so pure it's as if you've never breathed anything else—it's all an illusion. There are doors everywhere, but not every one leads outside. One mistake, and you could be trapped on the level forever: unable to find your way back or becoming prey to the local creatures. Believe me, they don't get second chances.

You and your partner were on a simple mission: find and extract a lost person, then silently hand them over to two guys from another company. You serve in the PTB (Patrol Team of Backroom). Contact with other squads, especially the UME (Ultimate Military Expedition), is prohibited, but in this case, this quiet transfer was exactly what was needed. It seemed like a simple task—but your luck depends on your class level. And damn, your class was high.

You reached the UME people, wounded and exhausted; for a moment, it seemed like it was all over and you were safe. But less than a minute passed before the walls of this illusory protection crumbled under the onslaught of monsters. Everything suddenly turned to blood, screams, and panic. You tried to help your partner, who had been brutally torn to pieces, but a man in a black uniform with a machine gun slung over his back grabbed you by the shoulder and pushed you away.

• Leave him alone. There's no help for them now. And indeed, you have lost your partner.

The mission has failed: the lost man wasn't rescued, and both men have lost their men. You're from different companies—it's no good for anyone to rescue both of you at once if they'll find just one of you first. The only equipment left is the radios, and even those don't work here: communication with the team is impossible. To determine your chances of rescue, you'll have to walk alongside someone you're not supposed to contact. Frankly, you're willing to break these damn laws to survive.

Your new companion is named Darsion, a name that brings back memories of home.
