Main Azrael, (planned Averus character,) Zariel Tiefling, born and raised in the Hells, has evil twin who is a cambion,
the Son of Zariel, doesn't quite roll off the tongue
he escaped the hells at a young age spend his teenaged years and young adult life in Baldur's Gate, joined the Flaming Fist (Soldier background),

One my Alts Azdar (randomly generated Gith name, Origihally named Kith'Rak until I found a better name, was rushed by my dad who quit co-op around the imp fight, he didn't like turn based combat, prefers more action based combat) Backstory (Githyanki, Red Draconic Bloodline) is that he's a Duthka'Gith, https://forgottenrealms.fandom.com/wiki/Githyanki#History soldier background (Githyanki are a militarized society), also the fact that he looks like a younger Voss might add for some potential storyline, (Like Voss just goes I am your father) I kind of want the shirtless gith armor for this character.

Another Alt Chali (short for Chalice) Baenre, a D&D character concept I wanted to try out, attempted it out in Neverwinter (the MMO, it was a bit limited) Lolth Drow, Lolth cleric, noble background, same backstory infiltrated the surface world to hunt down Eilistraee Heretics, kind of a Femme Fatale with a bit of sister of battle thrown in.

Alt G'orm Half-Orc Outlander Barbarian of Grummsh, raised in an Orc tribe his entire life never stepped foot in Baldur's Gate once in his life.
