Hello this has been bothering me for ages. I used to love this cartoon it was made in the 80's or 90's. These kids were sent to a magical world, think their mission is to try and get home and to help them in their quest they have a magical wepon. The only wepon I recall is an invisibility cloak which the female character wore. They also meet a unicorn called something like shila? It was a really good cartoon but can I remember what it was ruddy called. HELP I'd like to know how it ends or how began as I clearly can't remember.

Sounds like Dungeons and Dragons (1983) (http://www.imdb.com/title/tt0085011/)
