Due to their proximity in Southern Ibabaw, the Garo and the Rumzquze have experienced a large degree of cultural and technological exchange.


Both the Garo and Rumzquze have long-standing beliefs in the spiritual aspects of natural objects. While the Garo normally assign spirits to all aspects of nature, the Rumzquze are more selective and choose only anomalous objects called vazůlav upon the landscape to be worshipped.


The climate can characterized as a series of stratified layers. The southern grasslands and rainforests are filled with edible plant life. However, Northern Exhpazixh is much drier and the desert and mountain-dwelling Rumzquze depend on the agriculturally capable Northern Garo tribes for a significant part of their vegetarian food supply. This has resulted in a steady exchange of food moving towards Olneůik and the Noneůik Mountains. To reciprocate, the Garo are provided with objects ranging from architecturally crafted stone pieces to metal farming tools crafted in Olneůik.


The spirit (Reniba) necklace associated with Garo nature worship has been passed to the Olneůik through these exchanges. Originally made of stone, wood and animal hide, some Garo have begun using metallic jewelry from Olneůik instead. Although not a traditional part of Olneůik culture, the necklace has nevertheless been borrowed as a fashion accessory.
