Omolon Tuonela SR4. "Tuonela" translates to "the underworld". In finnish 'mythology' and folklore, it was the kingdom of the dead where the shadowy ghosts of the dead travel and wander around. Didn't matter if you were good or bad - when you kicked the bucket, you went down to Tuonela. The rulers of Tuonela are Tuoni and his wife Tuonetar. Sometimes, living people found ways to visit Tuonela to gather information and spells, and the trip there requires weeks of trekking in a desert, and finally the crossing of the river with the help of a ferryman. Shamans could visit Tuonela by falling into a trance and tricking the guards. The more you know!
