The characters two of my friends and I used during the previous season of our LGS's unofficial Adventurer's League. From left to right:
Twiip (thri-kreen soulknife rogue): The unholy progeny of two driders. He was rescued by Valatar and brought to the surface, where he grew up in Waterdeep and became part of the assassin's guild.
Valatar of House Auvryndar (mark of shadow elf conquest paladin/hexblade warlock): Youngest son of Vlonwelv Auvryndar, the matron mother of House Auvryndar in Undermountain and sibling to T'rissa, Sylkress, Pelonia, Melith and Ranaghax (these are NPCs from the Dungeon of the Mad Mage adventure book). When his soft-hearted rescuing of Twiip was discovered, he was cursed and exiled from House Auvryndar in Undermountain. Out in the open in Waterdeep, he attracted the attention of rival Drow houses, who sent assassins after him - including Twiip. (Valatar was my character)
Ilivarra of House Auvryndar (drow twilight cleric): Daughter of Shyntlara Auvryndar, the matron mother of House Auvryndar in Ched Nassad. When word of the hunt on Valatar reached Ched Nassad, Shyntlara dispatched Ilivarra to Waterdeep to keep her cousin safe.
