Thus, Lir is a shapeless god of the chaotic sea. For more on Him, see here. He seems to have met His match in a Bronze Age sea god imagined by SM Stirling:
"The enemy ships were gliding closer. On each stern was a small platform with a statue on it, a grotesque juju with three legs, six arms, and a single staring eye - Arucuttag of the Sea, Lord of Waves, Master of the Storm, to whom the captains gave gold and man's-blood."
-SM Stirling, Against The Tide Of Years (New York, 1999), Chapter Eighteen, p. 282.
The captains throw gold into the sea? And practice human sacrifice? Some gods need to be reminded that we imagine/create them, not the other way around.
Apart from the arms, the physical descriptions of Lir and Arucuttag are identical: one eye and three legs. One eye means focus. Three legs mean mobility. It would be an easy matter for the Ysans to recognize these two deities as different Gods representing one Being. See here.
