One Not of Pyrria

Personal Info
Name: Lucius
Alias: None.
Age: ???
Gender: Male.
Sexuality: Heterosexual.
Personality: Lucius barely knows how anything in Pyrria works. He has the mind of a child for the moment, and he needs someone to guide him. He is complicated though... Some part of him still wants to return to the Void to gain his full power, and he must fight this for as long as he lives. He still doesn't understand some concepts, but he is a fast learner. He wants to know everything there is to know about his new world...
Interests: He likes learning anything he can. He likes changing into different creatures to experience different parts of the world. Anything he can do to understand the world of Pyrria interests him.
He enjoys exploring and hunting as well.
He likes shadows, darkness, nighttime, anything to do with darkness.
He likes seeing new things and experiencing new feelings. Anything new to him fascinates him.
Dislikes: He dislikes bright light, but warm firelight, and the light of the moon and stars is fine.
He gets annoyed whenever he can't figure something out. He likes to be able to know everything that he can.
He isn't afraid of the dark, but he is wary of what lies within.
Fears: Not much yet seeing as he doesn't understand death, time, or anything much else about the world of Pyrria.
He does fear what might be lurking in the darker parts of his own mind.
He fears the fact that he might one day have to leave Pyrria...

Tribe Information and Status
Tribe: Rogue, for now.
Inheritance: How should I do this... He's not from the world of Pyrria...
Rank: None.
Family: All other Nightmares.
Mate: N/A
Hatchlings: N/A

Skills and Abilities
Strengths: He can change his form and body at will.
He easily takes to any magic dealing with darkness, concealment, and fear.
He's a quick learner, and he's curious about everything.
Special Abilities: Nightmare Shifting: He has the ability to shapeshift into any form that he wishes, for as long as he wishes. Once he settles on a True Form, certain types of magic(eg. light, detection, other types that reveal secrets.) will reveal his true form and force him into it. He will settle on a True Form as quickly as possible through RP. Until then his True Form is of a similar appearance to an Obscurus from Fantastic Beasts (Seemed fitting to me).
Weaknesses: Light magic and other types of secret revealing magic will reveal his True Form.
He is weaker against magic that is powerful against darkness, shadows, and other Nightmarish things.
He has about the understanding of the world that a young hatchling might.
He doesn't know how to talk.
If found and mentored by the wrong person, he could become a dangerous weapon.
His curiosity can lead him into situations that could harm both himself and others or can just lead him into situations that are just plain awkward.
Combat Style: He doesn't really understand the concept of a fight or how to fight. He would fight defensively and he would try to run, hide, and evade.

Background
History: Lucius is a creature created from pure dark magic that congealed around a point of complete emptiness known as the Void, or rather, not known at all by most. He would have been created inherently evil if not for a star going supernova. The blast flung him away from the Void on a path that would eventually end on Pyrria. He doesn't have a true form and is able to take any form that he wishes without serious repercussions. He has about the understanding of the world that a young hatchling would, and he needs a guide and teacher to help him become part of his new world. As far as he knows, he came from a world covered in darkness with only tiny lights in the distance (space). He has decided that he likes Pyrria and wants to stay, but something is driving him to leave...

RP Sample: It's alright to just say 'Refer to other apps' here right?

I'm not sure, but I have a feeling this might take a while to get approved... Bump!

You need an age and height and appearance. You put that he easily takes to magic dealing with darkness, concealment, and fear. You need to list every magic spell he can use and what they do. Because he is a new character, he can only have 1 ability, which means you need to choose between magic and his shapeshifting ability. If you choose shapeshifting, there needs to be a weakness other than your true form being revealed by magic, like not being able to stay in your shapeshifting form for as long as you want.

Also, you need to put a link to your other characters.
