Ivelyn is a more recent D&D character based on my fursona. These are the tokens I've made to use when playing with my group online.:

In her young adult life she had found hidden texts about this secret Ghost-Slayer society that has since vanished. After years of deciphering those texts, she has the steps to this initiation rite, though not really knowing the true meaning behind it. Deep within a crypt, this rat woman kneels inside this runic circle that she had replicated.

Ivelyn recites several verses of a language foreign to her. The runes glow. Success. And then pain. She writhes and wails, her screams bouncing against the stone undercroft. Arcane runes manifest around the spell circle and carves themselves into Ivelyn's flesh. She collapses drenched in her blood.

She wakes with this dreadful understanding of the line between life and death. And this ritual was an exorcism on her soul, and the runes carved into her body are meant to keep it contained. She now lingers on this line thereafter.

Her eyes have turned into this brilliant light blue, but seem dull and glazed over all the same. Her change in perspective and personality kept friends and family away. She doesn't spend her days within towns and cities, but within the wilderness. When she uses her newfound blood spells, the runes begin to bleed with growing intensity the more often she uses them.
