As fan of the old Phantasy Star series and Lovecraft, I've been looking forward to this AP since I first heard about it. It's going to be the first PF AP I've ever DMed, so I'd appreciate some feedback on this.
1. Eventually providing a fortunate/unfortunate PC with fast healing in radioactive areas.
2. Given what the AP reveals about Unity, I want to provide some way to get the machine race thriving on The Horse involved. The Distant Worlds setting explains they have a fascination with Divine Spellcasting. Possibly bring one of those robots back to Golarion.
3. Haven't seen it in the AP, yet, but intelligent robots should have the ability to cast arcane spells. Might be funny to have a Star Wars mouse droid equivalent break out a Color Spray on an unexpecting party.
4. Drop a vague hint that it wasn't the desperate actions of the Divinity's crew that allowed the ship to escape the Dominion of the Black, but was Aroden intervening to save the ship and send it to Golarion. Would that cause any major conflicts with the existing lore?
5. As circumstances allow, bring a PC back from the dead via "renegade nanites," but afflict them with some form of madness, as laid out in the rule books.
6. Have an easter egg area discoverable by the PCs that functions as a failed robot prototype museum and includes some suspiciously familiar robots that attack the PCs. Think the killer robot from Disney's The Black Hole or the one from Lost in Space.
