Okay, I have 2 customs who are based on Greek/Roman mythology. They are both sea nymphs called Nereids. They are like a human version of a mermaid (meaning they have legs, but they can stay for long periods of time in the sea, but can walk on land as well.)
One's name is Halie she is the eldest, but is the 49th of 50 sisters. She's 200 years old, but looks 18. Her birthday is July 14th She can manipulate water, but also can freeze it when the moon is full or a solar eclipse. She uses a weapon called leviathan reigns she wears in her hair. Halie uses it as a grappling hook, a whip, and a nunchanku. She's very wise and loves to help others, but she hates being flirted with and is haunted by past memories of her family rejecting her for disobedience.
Halia is a 12 year old and number 50 in the group. Her birthday is June 13th. Halia carries around a shepherds crook as a way to get around because she is blind, especially on land, but will rarely use it as a way of hurting others. She uses waves on sea as a form of echo location. She can use sea water, but uses sound as a way to destroy her enemies. Halia has a childlike nature, which is a double edged sword. Whatever anyone ever does, do not give the child sweets.
Whenever I figure out how to put my pics on here, I'll show them. Otherwise, what do you all think so far?
