Inyan remembered the trouble he brought upon himself when he created Maka, and he determined to create a being unlike any other to be his aid and do his will. He made a shapeless creature and named him Wakinyan (Winged-one or Thunderstorm). Wakinyan is as shapeless as a cloud and terrifying to behold. He has two wings of many joints, which he can spread afar or make very small; he has neither legs or feet, but has huge talons that can pierce the hardest of things; he has no mouth, but has a huge beak armed with sharp teeth that can rend and tear the toughest of things; he has no throat, but has a voice that is the thunder; and he has no head, but has one eye, and the glance of that eye is the lightning.
