A brand new RISC OS isometric 3D quest game been released for beta testing.

" For some years you have desired to be an apprentice Magus studying magic and lore. However, whilst you have friends within the academy, your abilities did not warrant being inducted when you reached adolescence. It was noted that you demonstrated skills at performing magic from ancient incantations read aloud and that the academy is still considering you since you show promise.

A number the alumni of the academy have disappeared recently. One, called Savid, returned distraught and explained that a dark magic was gaining acceptance. Initially word had spread that a new method had been discovered that appeared to improve self control and dicipline. But it appears that this method caused the practitioner to eventually succumb to another's will. Not just anyone, but one who had in fact long been banished. This person, Kimyani, had meddled with dark arts to the point that he 'faded', that is he became undead. He was cast out to a distant dimension where he could inflict no further harm. However, it appears that he has found a way to reach out to our world.

Unfortunately no-one listened to Savid. Except for you as Savid was your close friend. He told you that he had discovered an abandoned island where the undead were rumoured to walk and where strange creatures lived. A doorway to the dimension where Kimyani existed could be found there, and this was likely what he was using to reach our world. This island held ancient magic, which could also bring you great acclaim. So you arrange a boat to drop you at the island and begin your quest..."
