|Obitus is a video game by Psygnosis, released in early 1991 for Amiga, Atari ST and DOS systems. It was also ported for the SNES, by Bullet-Proof Software.|
King Cullen passed control of the peaceful land Obitus to his four sons, warning them to stand united or the land would fall into evil hands. To symbolise the unity, the king gave each of his sons a Gem of Tranquility, which when joined conjured a mystical force to protect the land.
Some time after the transfer of power took place, an enchantress named Salome sought to take advantage of the princes' fraternal pact. She told them each in confidence that they must break from the others in order to obtain personal wealth and power. The princes took these words to heart and fought for control of the kingdom. When the battle was over, each prince had one of the gems and one quarter of the land. The power of the gems had been broken. Only by reuniting them in the Tower Obitus can the kingdom be saved.
