[This is the last of my stash I had. I haven't drawn things in a while, I'm trying to get better though, I'm sorry.]

Obsidianna doesn't personally guide every single soul to the afterlife for rebirth, she mainly has the process done automatically. This doesn't mean she won't visit someone in their last moments to guide them however. Her priests and priestess get special treatment, but sometimes people just want that extra hour or two of life.

Obsidianna in the early morning arrives to collect the soul of a priest of hers, their time was up and she wanted to give them a comfortable chat as they traveled to the afterlife. But they wanted to live just a few hours longer, so Obsidianna was temporarily sealed away by one of her own priests.

A cleric using their powers on their deity? Funny.

She scolds them for this, she even dressed casually for things to go by nice and simple. Alas, she's stuck in stone stocks as her target leaves for a few hours. She forgives him, mortals will always have a fear of death after all. Just need to wait this out! It'll be alright. Just a few hours of minor embarrassment is all.
