Why the Crystal-Tree Grotto Stays Locked Until You Finish This Quest

You can practically stand on top of the Crystal-Tree Grotto and still miss it. The game won’t let you in, no matter how much land you’ve explored nearby. The same goes for the Waterway to the Falls. Both locations only open after you complete the world quest Let Not All Rivers Run Dry. No currency or resin cost is listed. The mission itself is the entire price of admission.

What the quest actually involves

This world quest lives in Novokitezhgrad. Public documentation is silent on some details, but the cast is clear: you’re joined by Thrud and Glinin. Glinin wants to survey how the local water behaves, and that survey becomes the whole reason for the trip. As you follow the prompts, the water study uncovers something larger concealed behind the flow. That moment shifts the quest from simple observation to discovery, and it’s where the mission really starts.

Expect a short chain rather than a one-step objective. The presence of two companions suggests multiple beats, even if the official time estimate is missing. The source also doesn’t specify how long the sequence takes, so don’t budget for a marathon.

What opens up after completion

Finish the last objective and the Crystal-Tree Grotto and Waterway to the Falls finally show up as usable places. They become open ground for exploration, with no further quest needed. For collectors, the grotto is also a known farming spot for Fairy Wormwood. If that material is on your shopping list, this quest is the key to a reliable source. The waterfall route itself doesn’t have a documented material link, but it’s part of the same unlocked bundle.

What to check if the route stays blocked

• The quest never appears. There’s no exact trigger listed for Let Not All Rivers Run Dry beyond its connection to Novokitezhgrad. If other objectives in that area remain unfinished, the game may be waiting on those. Check the quest log and keep track.
• The grotto won’t open after playing. Being in the middle of the quest isn’t enough. The area opens only when the quest is fully completed, not when you’ve activated it. Double-check the log for a clear completed state.
• You’re in the wrong spot for farming. The farming route for Fairy Wormwood points to the grotto specifically. If your goal was collecting that plant, double-check that you’re inside the grotto and not the waterfall route. The grotto is the source mentioned in the article.

Details that stay quiet

A few questions about this area have no official answers. Can you enter the grotto without the quest? No. The requirement is explicit. Is there a daily reset or time gate? Nothing in the official materials mentions one. What about co-op access or quest rewards? Both are left out of the known information. The same goes for a precise time estimate, though the two companions make a multi-part sequence likely.

The takeaway

Let Not All Rivers Run Dry is the only confirmed way to reach these two zones. Open the quest menu, follow Thrud and Glinin through Novokitezhgrad, and let the water survey play out. When the mission completes, the Crystal-Tree Grotto and Waterway to the Falls are permanently open for you. That single completion is all it takes.
