Horu, the Sky God (天空神ホル ), also spelled Hols in Ys SEVEN, is one of the three deities worshipped in Tritheism, alongside Grattheos, the Sea God and Maia, the Earth Goddess. Very little is currently known about Horu.
Real world analogue[]
Judging by his name and his domain, his real world analogue might be Horus, the ancient Egyptian god of kingship and the sky.
