Grez Thornscale was raised as "Grezzle Thurmhill" by a halfling couple who found a baby drakonid (Dragonborn) hatchling on the roadside, by the wreckage of a recent attack. Sadly, youngling's mother was killed in the raid but was successful in hiding the child.
The Halfling couple, Arno and Uma Thurmhill, used to be adventurer burglars and taught their skills to the orphaned drakonid as he grew older. At the age of 18, Grezzle knew there was more to life in the rural countryside where the Thurmhill couple retired to from their adventuring days and wanted to leave. Knowing the rogue life themselves, Arno and Uma allowed their young drakonid to set out, constantly warned him of the dangers of being a rogue.
Grezzle traveled far and wide, did some odd jobs here and there. He had to go with a different monicker as his reputation grew. Knowing that he was no Halfling, he went by the name "Grez Thornscale".
When he finally reached the largest cities, that's when he finally "struck gold", as they say. For a time, he worked for a criminal organization, but ran afoul with the mob boss and some of the women there. Grez Thornscale made use of his rogueish abilities and his integrated halfling background of luck to escape the city far, far away.
Rumors say that he perished when the mob finally caught up to him. Others say he was employed by an adventuring group as their personal burglar. Another rumor states that he was seemingly last seen in a far-away city beyond the desert. Who knows? The drakonid is "a slippery lizard" as they say.
