Triglav is a really old story that people from Slovenia used to tell. He's a god with three heads, meaning he has three faces! He's different from us because he's the boss of nature and people used to think that, if they prayed to him, he could control the weather and make all their crops grow better.
Triglav's three faces each represent something different. The first one is all about power and strength, the second one is about kindness and wisdom, and the third is about seeing into the future. People used to think that they could pray to whichever face they needed help from the most.
Even though Triglav is a myth, he was really important to the Slovenian people. They used to think that he controlled the world and that he was the only one who could keep them safe. Nowadays, people don't really believe in him anymore, but they still think he's pretty cool!
