A big adventure map what takes place on a big island called Island of Horna. The players want to become famous on that island, but the only way to be famous on that island is to finf the seven gems.
These gems are enchanted with some kind of curse. Whoever takes these gems from their home prison will be possessed, and the taker of the jewels will start to export the gemstones into their home temples.
When all of these gems are in their home temples, they will combine their evil powers and magically a big nether portal appears in the middle of the island.
A team of adventurers found the gems and they tried to export the gems into their homes. Luckily they failed in this life-threatening task and the gems are probably in the grasp of mobs. Your challenge is to find the seven gems and prevent the chaos from occurring.
