A half-elven mage driven from his home and forced to live among the "lesser races" due to his species, has devised a plan to get revenge at the elven nation who condemed his family for willingly mixing human and elf blood. By stealing a scroll of suggestion and getting a noble elven child in the capital of the elven nation of Turmok to put a portable hole into a bag of holding, he created a two way gate to the astral plane. Creatures began pouring out, and chaos ensued.
8 months later, the elves have lost most of their land and people, and their neighboring nations refuse to aid them due to the elves hostile attitude to other races, although some members from the nations have come to help the elves. The few mages left have discussed that by freeing an ancient, powerful beast from it's slumber (the tarrasque), they could guide it to clear a path to the capital and give them a chance to close the portal. They face fierce opposition from not only the creatures from the astral plane, but from what could happen if they fail to control the creature. The site is rather far from the elves war camp, but the magics guarding the place would take great heroes to survive, and so the king has asked that that any who are brave enough to step forth.
