Now that you've cleared out the Sky Base you can, in theory, dispel the clouds enshrouding Seraï's World and let the sun through. Alas, the party is not smart enough to operate the controls in Sky Base. You'll need someone smarter to do the job.
Use the teleportation pad in the campfire room to zip back to the entrance of Sky Base. The Speedball Network has now expanded, and you can use it to jump straight to the vortex leading to the Sea of Stars. Check to your left in the Speedball Network Station for a chest containing a Data Strip, then jump in your boat. Sail into the vortex and it will take you back to Home World. Head east to Mesa Island and use the shortcut to the east of Mesa Hike to return to Clockwork Castle.
Go straight north through Clockwork Castle - perhaps picking some ingredients along the way - and you'll wind up in the workshop with the kids after a few rooms. Speak to Caël, the kid in charge, to trigger several cut scenes. You'll zip to Mirth for a bit. Speak to Hortence once you regain control for a return trip to Clockwork Castle. Wacky science follows, and you'll meet a new creature known as the Artificer. It will join the party as cargo.
Use the vortex to travel back to Seraï's World, then use the Speedball Network to jump to the Sky Base. Return to the Catalyst's chamber via the teleporter and inspect its console for a cut scene. This will shine some sun on Seraï's World - and open the way to your next target, the Dweller of Dread. Its hiding spot is in the southeast of the map.
Infinite Abyss
Sail over to the Infinite Abyss - yes, that's a moon - and head for the vortex. This area is not a dungeon, and as soon as you enter the vortex you'll be facing off against a rather terrible enemy. Make sure your party is healed, equipped, and ready for what is to come.
Prepped? Then let's go. You'll face a trek west of your landing spot, then a brief swim through the Infinite Abyss. Once you drop down to a plain surface you'll be ready to go.
Dweller of Dread
- 1,100 (Tentacles)
- 210 (Valere / Zale Copy)
Once again, a Dweller does not disappoint. The Dweller of Dread is a multi-phase boss, similar to the Catalyst that you just fought, but ultimately tougher. Be ready for a slog. The Dweller of Dread uses the following attacks:
- A single-target tentacle slap (Tentacles)
- A single-target spine blast (Tentacles)
- An AOE swallow attack (Dweller of Dread)
- Dread Stare, a five-Lock attack that pits one character against a copy of another in single combat (Dweller of Dread)
The first phase of this battle has you fighting a pair of Tentacles. They're fairly simple melee opponents. The second phase consists of two more Tentacles, and is the same as the first. Things don't get interesting until the third phase, when the Dweller of Dread's main body comes out to play. It is accompanied by two more Tentacles.
