AS-IGA is a benevolent old water god who lives in the River Ob in Siberia. He provides blessings and benefits to the Khanty (formerly Ostyak) people of that region. These are mainly fish-related.
The Khanty have a special Fisherman’s Feast at the river on Midsummer’s Day which involves plenty of drinking and frolics. We hope the old man is invited.
