When we finally reach the Labrynth, we must find our way through - everyone takes a different path, people get trapped in those dungeons and need to be rescued - riddles, the bog of eternal stench, etc.
Finally, we make it to the castle, assault the walls, then break into the Escher room - were we fight "The Guardian" - he'll be the enemy leader, or just some illusionist spellcaster that warped the reality - after he is defeated, the "god" breaks out, teleporting everyone into a gigantic gladiator arena, where everyone must work together to defeat him
good diarrhoea?
