Our Lady of Being a Lich

Spoilers for everything ahead
Spoilers for all three campaign time periods exist ahead of this, so you have been warned, etc.

Visual inspirations for her
The depictions of Lucretia from The Adventure Zone resonate with me pretty well when I think about Our Lady of Being a Lich, particularly thanks to the fact that you get a lot of young/old side by side pictures of her.

Personal Info
If you really DESPERATELY need a name, she doesn't mind being called OLBL (prounced Ol-bel, sounds like Opal, so Opal is another option).
