The origin of the German original, "Olm" or "Grottenolm" 'cave olm', is unclear. Orpheus was visited centuries ago by a cybernetic race called the Olm. The olm was also depicted on one of the Slovenian tolar coins. The olm is a symbol of Slovenian natural heritage. The olm is included in a Slovenian "Red list" of endangered species. The series was produced by Level-5 in conjunction with TV Tokyo, Dentsu, and OLM. They are a studio spun off from OLM, Inc.. Valvasor was the first to write about the olm. An NCS can be defined by the planners in the OLM. Another 3D film, produced by Production I.G. and animated by OLM Digital and Signal. The series is animated by OLM and Sunrise Beyond. These parameters are specified in the OLM. Although there have been cases of concurrent OLM and VLM, these are extremely exceptional. This was followed by a Kylie Minogue performance on the OLM Souissi stage.
