This is a guide for Chapter 4 of Xenoblade Chronicles 3, covering the exploration of Syra Hovering Reefs in the Keves Castle Region. Also, how to sneak into Keves Castle.
Where to go after Moebius O & P
After thrashing Moebius O & P, you’ll regain control near Engardo Pass Camp. From here, the exit that leads to the Keves Castle Region is a stone’s throw away to the south.
Upon entering the Keves Castle Region, you’ll be at Syra Hovering Reefs. First, head south-east towards a bridge that leads to the castle area. However, heading that way would be unadvisable. That said, you can go that way to trigger Ashera’s Hero Quest (you still cannot reach the castle though).
Instead, ride the zip-line to the south towards Hovering Reef 7, then make your way anti-clockwise along the other hovering reefs, till you reach Hovering Reef 2. While you’re adventuring, be care not to fall off the edges (or get excited and jump off the zip-lines) because there aren’t any landmarks for a while.
Only when you reach Hovering Reef 2 can you relax, because that’s when you’ll discover the Hovering Reef 2 Camp. Get some rest if you need, then continue south a bit to trigger a cutscene.
How to Sneak into Keves Castle
Next, you’ll need to infiltrate the Ether mine at Hovering Reef 1 towards the north-east. After riding the zip-line, there are two routes you can take. Nearby to the north, there’s a shorter zip-line that leads to a bunch of enemies. This path is shorter, but riskier. That said, if you’re overleveled from quests, you should have little issues.
Otherwise, if you go east, there’s a climbable wall that leads to higher ground, allowing you to circle around a bunch of foes. From here, you can travel anti-clockwise around the reef. This path is longer, but there are minimal foes to deal with.
Either way, your target is the north-west corner of this reef, where the cargo crates and transport vehicles are. Once you’ve reached the destination, the gang will sneak into the crates and be transported into Keves Castle proper.
