1. Introduction

Krogdalo's Sanctuary is a Treasure Item in Black Desert that allows you to switch Mythical Horse at any time

In order to craft a Krogdalo's Sanctuary, you'll need to own all 3 of the Tier 10 Mythical Dream Horses
The Krogdalo's Sanctuary acts as a portable storage keeper, letting you check in or take out your horses
You'll also be able to obtain a unique title and furniture like with the other available treasure items
This let's you use the best horse for any given moment but realistically it's just a nice bonus to have

2. Krogdalo's Limitations

There's some basic limitations that are in place for the Krogdalo's Sanctuary but they're all ones that make sense.

If you have retrieved any of the Mythical Horses from Krogdalo's Sanctuary, you can't store Krogdalo's Sanctuary in the storage.
You cannot retrieve Mythical Horses in the Red Battlefield or Battle Arena where mounts cannot be used.
You cannot store Mythical Horses carrying trade goods in Krogdalo's Sanctuary.

3. How to Obtain Krogdalo's Sanctuary

First, you'll need the three Mythical Dream horses, one of each type. That's obviously the bottleneck to getting this treasure item.

After that, all you'll need to do is ride one of your three Mythical Dream horses and visit NPC Merindora in Grana to start the quest line to unlock Krogdalo's Sanctuary.
