In the origin of fire story from Yap in Micronesia, Yalafath is its source though the unfortunate thunder-god is the direct donor. The root vegetables, taro and yam, were eaten in Yap but fire to cook them was not known. They had to be baked in the sun. The people were wracked with internal pains and asked Yalaftah for help. At once a red-hot thunderbolt * fell from the sky into a pandanus tree. Prickles burst out of the sides and middles of the pandanus leaves. The thunder-god Dessra, found himself caught in the tree and called out for someone to come and release him. A woman names Guaretin, who was sunbaking taro nearby, came and helped him. He asked here what work she was doing. When she told him, he sent her to fetch some moist clay and he formed a cooking pot. Then he told her to get some stickes from the arr tree which he placed under his arm, implanting in them the seeds of fire. This is how clay pots came to the Yap and how it became possible to make fire by the friciton of wood.
