D&D Commission: Alvicarion, The Dragonborn Tempest Cleric

Vic was a sailor, not a captain, not a useless deckhand. He encountered a raging
storm on the seas, and it sunk the ship. Everyone aboard drowned, except Vic. He managed to
get a hold of a large turtle, and he clung to it and was carried to an island, surviving the storm.
He attributed the helping turtle and his survival to Zeboim, the Goddess of the seas, storms
and so on. And since then, he was her faithful Cleric, a Tempest Cleric.

He later had to eat the turtle to survive (or maybe he was just hungry, no tears were shed), but
he kept the turtle’s shell. He uses the shell as a massive shield.
