Daedalus

It is unknown whether the first dungeon created was made by Daedulus or whether it already was Daedalus. It is said that any obstacle that stops you from getting to your destination was placed there by Daedalus. Daedalus is a tricky god, it does not necesarrily want to stop you from getting to your destination but won't mind if you get lost getting there.

But, all of these obstacles placed by Daedalus do not compare with Daedalus itself, an intricate infinite labrynth with no way out, getting trapped in the deepest part of it, none have made it out.

Except for Minos.

It is unknown whether Minos and Daedalus are seperate in their divinity.
