Ley lines, lines of magic energy, criss-cross the earth forming supernatural geographic areas such as the Bermuda Triangle. Points where ley lines intersect, called a nexus, are places of powerful magic, such as the Pyramids of Giza and Stonehenge. If a ley line nexus grows very strong, the very fabric of space and time can be torn thus creating a rift, a hole in space-time leading to another place, time or a new or parallel dimension. Ley Lines are normally invisible, but in the magic-saturated world of Meriga, they become visible at night as massive bands of blue-white energy half a mile wide and stretching for many miles. If the magic nearby is extremely strong the Ley Lines could be seen during the day too.
Years ago, from one of these came, the first Xicitix. They created the first hive-city, who outsiders also the Mother-nest or Capital-hive. In a few years it grew to a gigantic size and some of them moved to a new site and created a new hive. Filled with efficiency and growing in numbers, the city-hives became a normal sight on the zone. Neighborhood towns started moving to avoid fighting the insect patrols. Few of the scavengers that were brave enough to enter the zone to steal from the Xiticix were known to return.
The Xiticx didn’t deploy emissaries, nor did they give any ultimatum. They were not necessarily evil, they were efficient. Their efficient in foraging, building and multiplying excelled any other ability. No communication was possible with the alien race. They’re mindsets been so strange that even telephats find few reference points to understand them and less to be able to communicate with them.
Only one race was crazy enough to study them, albeit from a distance. For years the Olympians spied on the Xiticix using robot camera-robots and satellite images. Infiltrated their nests in disguise and even provoked attacks to study their combat efficiency. From time to time they caused natural disasters or plagues that kept the population grow of the Xiticix under control. If wasn’t for these “scientific” approach of the Olympians half of Meriga will be covered in hive-cities.
But the Olympians lost more than 75% of their resources in their battles against the Kartographers, a band of adventurers that showed the habitants of Meriga that the Olympians weren’t the gods they claim to be, but a group of scientist with enough Tech Level 9 devices to pose as gods. Now, 10 years after those battles, the Xiticix has grown without control and are ready to move east and be as “efficient” as they always are.
