Congratulations, we are pleased to inform you that you have been hired by Dungeon Company. Please go to the Human Resources Office tomorrow to complete the on-boarding procedures and coordinate your schedule. The company will assign you a portion of trial employees to help you build your own team and maintain normal operations.
In order to protect the property of your company's clients, you will fight off human warriors, use magic, traps, and fights, and use all means to get them out of the dungeon or die here.
Remember, even the smallest mistake can ruin your entire career.
Good luck, new member.
