He has nothing. Not even his body. Sometimes Cazador prefers his metaphors a bit more literal- though Astarion is sure it hadn't been intended for this particular punishment to persist as long as it has. It marked him as property even hundreds of miles away, and ostensibly free.
He'd intended to deal with it quickly and quietly.
He should have known better than to hope he could preserve his pride.
The Underdark is filled with mushrooms. Mushrooms that explode. Mushrooms that choke you with noxious fumes. Mushrooms that...send you spiraling into an insatiable heat?
Well. It wasn't Astarion's fault that he had fallen into a patch of said fungi. But at least the selfless druid was there to help.
Astarion, with inspiration from Sebastian, kills his master, breaking the cycle of death he's forced upon his spawn. With no clear path ahead of him, he reunites with his parents and they help him settle in this new nighttime life he faces.
He opens up a tailor shop in Baldur's Gate, encouraged by his parents. Over the years he meets each of the core companions... and falls for a certain large elf who comes in for more 'civilized' clothes for a conference in the city.
