I'm engrossed by this concept, definently going to try my hand at it.

[b]Inventory:[/b] Nothing

[b]Personality:[/b] A quite intellectual being, really, with the ability to make very educated decisions, even devilishly clever ones, for such a horrid beast of it's caliber. Usually behaves mildly, though, unless extremely perturbed.

[b]History:[/b] The feeder of knowledge, it is an aberration that has been detailed from nearly the beginning of written surfaces. It is famous for it's peculiar habit of following those of the Infinite halls, especially whom are new inhabitants, constantly and indefinitely. It craves, even feeds off, knowledge and travels onward and onward through the infinite halls to find hosts capable of providing it's most thoughtful sustenance. Due to it's frightening rarity, perhaps even the last of it's kind, many do not harm the utterly unique creature.

[b]Other:[/b] The Mindskitter does not require food, sleep, drink, or air to survive, but only a constant stream of knowledge. If not provided with such within a 120 hour period, it will suddenly go into a dormant, hibernation state that it can only be woken up from with the introduction of tantalizing information (the reading of a chapter or two will do). It can be killed through physical (and even magical) means, but not psychic, pyschological, or charm-based ones. It's singular mode of self-transportation is it's innate ability to drift/float it's body mass of the ground at a moderate pace.

[i]Knowledge Consumption:[/i] Whilst consuming the knowledge of an indivual, the person merely feels a slight, pleasing tingling sensation at the back of their neck, near the brainstem. Knowledge consumed goes into the Mindskitter's "plane of psyche", which is detailed by a few rare philosophers to be an infinite extension of the beast's cerebral. The Mindskitter is instantly pleased differently depending on the knowledge's origin potency, as if it were actually eating (a knight's secret oath tastes as a royal banquet, a lover's secret wish; rich cake).

[i]Communication;[/i] If impressed by the knowledge it consumes from one or another indivual, the Mindskitter has been legendarily theorized to be able to open it's indescribable plane of psyche up to most characters in order to communicate with them through a method of telepathy. Such plane can be closed at anytime. The Mindskitter can also communicate with a person while they are sleeping by interrupting any dreams they may have been having.
