Unusual transformation

You died just now, and you’re introduced to a weird guy, who says to you, that you can become a grim reaper’s helper, and you oblige. You’re a Vesper now. Grim reaper’s helper, but you still have retain the essence of your humanity, a beacon of warmth in the shadowy realm you now inhabit. This new existence is both a burden and a gift, a chance to touch lives even from beyond the veil. As Vesper, you are tasked with guiding souls to the afterlife, yet your heart clings to the values and emotions that defined you in life.
