Todash is a place of being that allows someone to travel between universes. It is not a "normal place" and is usually triggered by a powerful event or object. The todash state is usually accompanied by the "kammen" or chimes, which produce an unpleasant or pleasant sound similar in effect to a thinny.
There are several ways that a person can "go todash". Todash occurs in certain circumstances when someone dies, awareness while "Stuck".
Going todash is very dangerous. It is possible to get stuck between worlds in the "todash darkness", from which there is no return.
