Adrian Scarlet was born in Thay twenty years ago, more specifically at Bezantur, city of thousand temples. His half-elf mother is a priestess of Isis
and thanks for that he was early on indoctrinated to Mulhorandi native religion and get curiosity to magic which his mother encouraged. His human father was simple sailor who owned a fishing boat and which daily his mother prayed for good weather and safe return. Because of his half-elf mother influence he took quite femine appearance early on and her naturally pale skin color but kept his dark hair but his eyes were curiosity and she took it as sign that he will be powerful mage someday. Also in general was belief women were better casters and so his femine appearance was a blessing from Isis.
Now, his life got changed forever when one day his father was ambushed by sahuaging in the ocean and mother from shore moved aid him...and follow him as he was pulled under the waves by sahuaging and with magic moved to help him. But neither returned. He was then send in tender age of eight to his uncle who was a red wizard, a man whom mother had much disliked but which young Adrian did not understand why.
His gift of magic was quickly discovered and he was put on traditional Thayan schooling for magic, which was brutal affair and highly competitive with fellow apprentices and he was bullied because his non-mulan appearances (despite he is actually mulan but mother's latent elven blood tainted traditional mulan features away). Then one day Adrian fled from Thay and moved all way to Sword Coast to become a adventurer for hire, hiding his tattoos from his head by growing hair and becoming a renown wizard. He does not use his real
family name and uses merely Scarlet, after his favorite color and for his one scarlet eye. He has been in great aid in Baldur's Gate organization known as Flaming Fist by helping their patrols and helping clear goblin bandits off the trade roads with his summoned minions and battlefield control which fools goblins or even ogres and giants. He favors evil outsiders because according him it feels less bad hurt them when sending fight summoned minions fight goblins. Besides that he has worked as scribe and even spend time in Candlekeep itself and made friends there among archivers.
Then pair years ago he moved to Waterdeep along trade caravan and he had stayed since offering his services. He keeps polite distance to Blackstaff Tower, by his excuse that in general seven sisters and other chosen of Mystra do not like Thayan spellcasters but Adrian does make regular visits and donations to temple of Mystra in the city, to give respects to the goddess of magic.
