Devin Walker

Devin Walker is one of the main characters in the book series Ventures of Gem Land by Janushi Raichura. He is the son of Haukea and Samuel Walker, the former rulers of the Element Water. His parents were killed by the Queen of Fear. He also has a sister named Layla, who was shown more powerful than him in Black Time. His real name is Helio, though he is called Laurent by Lucinda once in Black Time. There is no info about his life until he met Lucinda, Jessica and Jackson when he was twelve and he went to Gem Land along with them. On his stay there, Lucinda developed a bitter rivalry with his sister and a great dislike for him. He was often asked about his mother by Lucinda, to which he always replied that she's dead. It's clear that this is a lie, since Layla repeatedly threatens him of their mother, and that couldn't be possible if she's dead. Devin also seems scared of his sister and mother because he is never shown standing up to them. Layla's threats seem a bit unusual since Lucinda stated that his mother, Haukea, often came to her aid in the past and that she had a kind nature. Jackson stands up against Lucinda when she speaks ill of Layla and accuses her of jealousy while Jessica takes no side in any argument of Lucinda and Devin.

After spending fourteen days in Gem Land, he parts from the rest of them and again, there is no mention of him until Lucinda finds the Book of Secrets and sees his name in the book and he catches up with the rest of them to fend off Black Time. He gains the power of Sapphire which bore the power of manipulating Electricity, electronics and teleportation.
