The Veil

The Veil is the name of the spiritual barrier that surrounds Mencu, put in place by the Serén at the dawn of recorded time. Its purpose was and has remained to keep out Leaxyk and any of the forces of Rorret. For the last approximately 997,000 years, it has done this job successfully. However, recent rises in spiritual activity have detected a weakness in the veil, over the Krippan city of North Serénes, where the veil is rather thin.

Mechanics
Death, whether natural or otherwise, weakens the veil as Serenghe spirits pass through it. Birth has this effect as well, although not as strongly because of the different states of the bodies and spirits. Some of the more spiritual individuals warn against wars for this very reason. Since the veil does not repair itself, nor are Tazakrelu and Ukezal able to repair it, any damage done to it is permanent. However, it has proven to be very resilient, with only one weak spot having developed in its entire history.

Forbidden rituals also affect it negatively, especially any that involve summoning or spirits. This is the primary reason that the Rites of the Ekae are considered taboo.

North Serénes
The veil over North Serenes is very thin because of the numerous wars that have happened there. No Serenghe has ever conquered the City of Legends, and so many a warlord has led armies against it in an attempt to be the first. The result has caused there to be a massive skew in death rates across the world, with Krippa having more deaths than the rest of the world combined, and North Serénes accounting for more deaths in Krippa than any other city or state combined.

Seers and Sages, (and sometimes even the Žkha), track the thinness of the veil frequently, and while they feel increased spiritual presence and influence here, there is no sign that the veil is goinjg to sunder as of the year 4648 of the 182nd Age.
