Northern Highlands

The Northern Highlands of Ethiopia is a bio-region within the country. It was once home to Trash Lord Colombo, who roamed the countryside, building prisons and terrorizing citizens. In 2024, King Jablowme commissioned Brett and Yarkahalla to go to the region and get rid of Trash Lord Colombo, and get the treasure. In Trash Video 6, Brett and Yarkahalla attack and battle Colombo, but fail, as he knocks out Yarkahalla, and runs away after Brett throws his knife, and captures it.

In Trash Video 7, Brett is stuck in the region, but is told by King Jablowme that there is a meeting of The Black Mamba, an organization set up to destroy the Trash Lords. Brett finally gets out after almost being robbed.

Currently, the Northern Highlands is mainly made up of herders and farmers apart of the Amhara ethnicity. Jablowme has also banned usage of the trails in the Highlands.
