Anti-beast trenches of Ganu

Ganu's wildlife grows naturally larger than other parts of Utea. The Segaii needed to protect their settlements from unwanted visitors or lost beasts.
Outside the log walls, deep sinkholes and trenches drew about 100 feet distance. These are either covered or kept open. Spikes and stakes were placed in the deep, waiting for unlucky animals and invaders. The safe way to the gates, since most regions lack roads, they are marked with Segai tribal signs.

The original trenches were more natural. The Segaii kept giant ant or wasp queens under the chieftains' houses, so the queens' colony dug a whole underground passage system around the villages. However, sometimes those beasts attacked not just the invaders, but locals too, or harassed homes and storage. The Segaii started making their defenses.

In the desert regions, the trenches are usually covered, so the sandstorms can't destroy them. Their bottom is deep but empty. In the jungles, the Segai like to use some deadly wildlife or sticky tar, to keep the fallen creatures at the bottom. Venomous snakes, mushrooms, and ferns with dangerous spores live in the deep. On the savanna, open trenches are common, with huge spikes in and around it. The Segaii harvests the meat of the hurt or fallen animals if they get caught.

The largest trench system is located around City of Vrikdarok. Close to 500 feet away from the most outer walls - since the city has a few defense lines - can find the farthest pits. Around the city, there are three complete lines of trenches, with wooden bridges over them. If the enemy comes towards the gates, the bridges will be destroyed first.

The Segai technology already spread through the region. The Bugits use similar pits to make hunting traps and keep safe their lairs. The Army of the United Nations uses trenches to move their forces outside the keeps, without alerting any watchful eyes.
