Delionis was the most active god when he was mortal. He helped found the city which was named after him, Leonis. Knights, nobles and scholars revere Delionis, as well as builders, some Gnolls and the majority of Dwarves. Being very single-minded, it is seen as strange not to worship Delionis as a Dwarf.
People pray to him for peace, to make the right choice, to bless a site when a building is about to be made or in thanks after graduating a school.
