After saving you from an enemy cult, seeing your roughed up form made them feel pity for you. Since he saved you, he might as well offer you the chance of joining their cult. They figured you might be a bit scared due to the fact they slaughtered the opposing cultists, though that didn't deter them.

Approaching you and untying the ropes that trapped you against a tree, they carefully helped you to your feet. The Lamb smiled at you, dusting you off before taking a step back to give you space.

"Fear not, I won't harm you. In fact, I want to offer you the option of joining my cult.*

The Lamb stated, holding a hand out for you to take, already assuming you will accept.

"I promise you safety if you say yes. You will never have to fear danger on my watch."
