I'll go first. He's a reborn necromancer wizard, with a 1 level dip into death cleric.
His backstory comes with a clichénwarning for lost memories..
He lost his memory just before the start of the campaign. He was conducting a gruesome experiment on a dog, when something went wrong involving lightning. He died, but also didn't, and came to wandering around his lab years later, clutching the skull of the dog, which had rotted away to just bone.
He didn't have a name at the start of the campaign. I let a different player name him, as his character knew mine from before the accident. He came up with the truly awful name Melvin Kingston, which I've grown to love. He had a massive fear of death, having died once already, and was quite the coward in early levels.
His memories have been slowly returning, and he's had to come to terms with all the evil things he did in his previous life. I recently took a level in death domain cleric, cos we had no healer, and I found the god Jergal, Scribe of the Doomed, who is concerned only with documenting the dead in his great book. Melvin's faith has allowed him to come to terms with death, and accept it as a part of life. (His newfound ability ro wear medium armor has helped as well, lol). I love having 8 cantrips, and so so many spells to choose from. I have so many options!
I love playing him, and I'm loving the progression he's gone through. I have more planned for him.
Now your turn!
Prepare to meet, Kyle the Audacious
Arlo Underbarrel was the son of traveling merchants. He practiced music, burglary, and intrigue. It started as sneaking into places to steal stuff, mostly out of boredom. You see, Arlo didn't have a difficult or tragic past. When he realized he could get easier access to places as a musician, and that as the hired musician he got into all the court gossip, he starts targeting nobility. He's chaotic good and wants to make the world a better place by bringing the system down, and that's easier from the inside.
Now grown up, while spending a couple years in the City of Dawn, he crossed paths with his now BFF, Chisuke (another PC). Arlo breaks into a room and is in the middle of stealing shit when Chisuke's mark comes rushing in and Chisuke comes in behind him and kills him. Arlo just stands there, gaping like a dumbass, jewelry box in hand. Slowly puts it in his loot sack, mutters something like "good thing this room is empty." and then dips out the window.
Then they start noticing each other at court functions - Chisuke, it turned out, was a Lord, and often crossed paths at parties where Kyle is the hired entertainment. Kyle would be down to help him break into places in exchange for the excuse to get away from the party with someone who belongs there and also, of course, the loot. Gotta have the loot. And if you gotta kill someone well that's cool too, but he hopes they're noble and deserve it.
Whatever timespan later - Arlo has decided he wants to change his life and become a bard. He begins his training at the Bardic College. When things go sideways with Chisuke's family, Arlo turns to the stories of the Halfling heroes he grew up reading stories of. He decides that he needs to recreate ehimself, and Chisuke should do the same, and adopts the monicker of Kyle the Audacious, modeled after Lyle the Magnificent. Chisuke he dubs Okami the Bold!
So mechanically speaking he's a Rogue 3 / Bard 3 right now. Arcane Trickster, College of Swords. Every round of combat he narrates. Even when he's stealthed, he can't shut the fuck up. He shouts "sneak attack!" every time he attacks, whether it's a sneak attack or not. Whether he's stealthed or not. Being as I'm also one of the only experienced players in the group comfortable with taking point he wound up being the defacto Face of the group. Which he has dubbed the Prose and Khans cause it's 2 bards and everyone else is some form of fighter or barbarian.
We play on discord/roll20 so I send all the narration to discord to save it. Here are some of my favorites
