Introduction
Presence Concealment is the ability using which a character is able to conceal or hide their presence by erasing their aura, sound, smell, energy, etc or by blending with the environment and be indistinguishable from it. This allows the character to remain completely unnoticed by others even if the character is standing directly in front of them. This ability is different from invisibility as the character is not becoming invisible but rather removing the traces of their existence and as such, even other characters possessing Enhanced Senses might not be able to find/sense the presence of the character.
Another form/sub-category of this ability is Stealth Mastery using which a character can go into a mode or form made for stealth, which allows them to casually slip past foes and get in and out of areas undetected. Enemies will be unable to detect the user, and the user is also able to be unnoticed in public, and not be tracked easily.
