The Crypt of Aura Von Stein

From publisher blurb:

Adelia is more than certain that her discovery is revolutionary. She does not dare to delve into the dark crypt by herself. Her research team is not prepared to deal with possible threats or monsters. So, she plans to hire a group of adventurers to help her. Little does she know that the security measures of the crypt she found are a way larger threat than what she thinks. Things go south. Her ambition blinds her judgment. She frees a demon from its prison, allowing it to unleash its fury and dark influence upon the world. The crypt belongs to Aura Von Stein, an old necromancer. It holds ancient relics and treasure, for those who can beat the demon and what lays beyond it.
