Scales of Justice
Verdigris was studying under the Maelstrom clan of Dwarves for his priesthood when they were attacked. The King and Queen of Maelstrom gave their son Rathgar to him and asked him to take him to safety.
Verdigris tried to escape the Gnolls, and headed into a forbidden area of the ice plains to try to get away. The cold was too much for him, and he collapsed on the ice, desperately shielding the baby from the elements.
However, he happened to die in the "forbidden zone", where Kyuzo the Silver slept. He was returned to life as the Silver Scale, and was given back enough energy to escape to the South.
He raised Rathgar in Morning on Crescent, never revealing his true heritage in the fear that it would put him in danger.
